ABSTRACT The peculiarities of the processes of structure formation in
water suspensions of Portland cement are determined generally
in the first stages after their production by aluminate
minerals, esepeclAaly by tricalciumaluminate. The study of
these processes becomes particularly interesting by the
circumstance that just in this stage the system wat;-r - cement
can be easily influenced in such a way as to regulate the
structure of the cement stone. In the case of a mixture of
1 - 5 % tricalciumaluminate and 99 - 95 % quartz sand, only
the former substance is responsible for the formation of the
structure, The great amount of inert filling substance
facilitates the study and a:)proaches the hydration conditions
of C2R to those of the cement dough. The authors characterized

influence of the wash- admixture in suspensions of tricalcium-
aluminate. On the one handq this admixture slows down the structu-
re formation and the hydration as well as the crystallization
of the new forms, on the other it causes an adsorption peptiza-
tion and a dispersion of the initial particles Of the C3A.
By this these processes are accelerated. Furthermore,
the wash blocks off the points of possible contact and loosens
the strength of the crystal structure. The total influence of
thewash depends on the predominance on one of these two factors,
in the case of one or the other concentration. Hydration slows
down and dispersion increases with growing concentration of the
wash. No water is bound during an induction period. Not before
this period is terminated does an intensiye hydration commence.
In connection with this process plastic strength increases and
leads to the formation of hydroaluminate. In the case of large
admixtures of wash strength may increase to 8-10 times its
original value. On +his occasion the hydroaluminate crystals

the microcrystals, i.e. the formation of crystallization con-

only a short while, Under these circumstances virtually no

PERIODICAL Doklaky Akademii Nauk SSSR,195T,Vol 115,Nr 3,PP 509-511(u.S.S.P.)
ABSTRACT It is usually said that the formation of calcium hydrosilicate
on the occasion of the interaction between limestone with silica
in the water medium by hardening of the binding calcareous-sili-
cious building materials can only take place by hydrothermal
treatment in autoclaves at temperatures of an order of magnitude
of 1700.kt normal temperatures this process is assumed not to ta-
ke place i.e.it is not expressed in a noticeable increase of
strength of the formedprpduotion. Some building productione,ae
e.g. wall blocks,which are used more and more in low buildings,
do not need the strength obtainable in autoolaves. On the other
hand,the papers of the authors confirm the assumption that,be-
sides a hydration hardening of the calcareous-arenaceous binding
Bubstance,the binding of the calcium hydroxide gradually develop*
in the surface strata of the sand grains.The better this surface
was developed and the more it was activated in the common break-
ing process,the greater is the quantity of limestone bound into
calcium hydrosilicate.By means of the radioactive isotope Ca45

ABSTRACT: The authors illustrated the following: The essential part of the
effect of liquid active lubricants at pressure working of metals
is not the exterior friction but the resistance of the treated
metals against the flow in a quite thin surface layer. This re-
sistance determines the intensity of the tangential stress which
occurs in the surface layer of the deformed metals. The liquid
active lubricants reduce strongly the additional shearing deforma-
tion of the surface layer of thettreated metal. The strong reduc-
tion of the "effective" friction coefficient (of the tangential
stress) is caused by the localisation of the plastic friction in
a thin layer of the softer coverin- metal. Stronger thinner cover-
a.-es (nitration, carburization, chromium plating) impair upon the
d.rawing process by intensification of the tan,-,ential stress. The

ABSTRACT: At first the authors shortly report on respective literature.
In the present works the monocrystals. of zinc, tin, cadmium
and lead (degree of purity 99.99 %6, diameter 0.5 mm,
length about 10 mm) were investigated. As surface-active
substance served mercury'which was applied in form of a
thin coating by means of immerging the sample into an
Hg2(NO3)2-solution. The mercury covered the monocrystal
with an equal film of about 0.1 g thickness and was rapidly
saturated with the metal to be investigated. The investi-
gation of the strength properties of the amalgamated mono-
crystals in their expansion with constant velocity showed
that the strength of the zinc- and tin- monocrystals

of the non-amalgamated monocrystals. Such an abrupt decrease
of strength is obviously connected with the important
decrease of surface tension at the metal/Mercury boundary
as well as with the decrease of the production operation
of a new surface at the crack. The investigation of axial
ground sections of amalgamated zinc-monocrystals according
to their deformation showed the following-- The cracks can
develop on the surface as well as in the interior of the
monocrystal, which can be seen in observing the axial ground
sections. The development, of the cracks in the inner parts
can be connected with a noticeable diffusion of mercury
into zinc (atroom temperature) with subsequent decrease of
the surface tension on the developing inner separation
surfaces. The rise of temperature up to 1600 C annihilates
the above-mentioned phenomena of catastrophic brittleness
with the zinc-monocrystals investigated and reconstitutes
completely the plasticity and the strength. Also the
decrease of the deformation velocity causes phenomena
which are similar to those developing with the rise of

ABSTRACT: The interaction between Portland cement with water takes place
without a perceatible induction period. The hydrophilic plastim
fiers (ligno-sulphonates of the "sulphite, distillerts washil, in the
following called SSS) bring about an induction period. This faet is
beside other favorable influences of these additions used for the
consolidation of the disperse structure of the cement stones In
spite of several works dealing with the part played by the SSS
(references 1-5) the.causes of the induction period remain unknown*
It is the object of the present paper to determine the part plVed
by the adsorption of the surface-active substan--e from the water
medium of the suspension on the developing small crystals and
points of formation of the new phase, the new hydrate formations.

content in the water medium correspondingly increased. This can be
done by the introduction of small quantities of salt whicli form

w�thout SSS, they are not capable of bringing about the induction
period, The calorimetrical investigation of the cement hydration
leads to the determination of the kinetics of the separation of
heat, (figure 3.). The addition of Ox5 O/o SSS leads to a shcrter
induction period, after which the hydration takes place more interp
sively than without such additions. The induction period is rapidly
prolongued by increasing K2CO3-additions. The separation of heat
during this period increases almost proportional-with the duration,

nates. The phenomena described raise the assumption that the begin-
ning of the induction period is caused by the presence of a hydro-
philic surface-active substance in the liquid medium of the suspens
sion. Thus the chief factors determining the duration of the induc-
tiomperiod of the cement hydration in the presence of SSS are:
a) the initial concentration of the plastifter in the water medium
of the cement suspension which is dependent on its total content.
and on the quantity of adsorption at the primary cement particles,
b) the velocity of the binding of the plastifier by developing
crystallization points of the hydroaluminate. It has to be pointed
out that the stabilizing actiom of the layers of adaorption, of the
Idgnososulphonates of the SSS also plays an obvious part in the
pL-:Lst:Lfyi-ng total effect. Thereby the formation of the coagulationa
structures is prevented. These layers may also slow down the dissom
lution of primary cement particles in the water.

ABSTRACT4 A study has been made of the strength characteristics of
milk fat and butter. It was found that in order to satisfy
the consistency of butter)the fat must form a mixed crystal-
lization-coagulation type of structure with the coagulation
structure predominating. The specificities of structure for-
mation in the production of butter by churningjand by the con-
tinuous chilling of high fat content creamphave been examined.
Two major ways have been indicated for improving the butter
consistency: controlling the crystallization temperature of
the milk fat, which allows changes to be made in the total
solid phase content of the system, and regulating the me-
chanical treatment in the hardening process, which allows
changes to be made in the character of the structure formed

ABSTRACT: All two-phase disperse systems can be divided in two groups
according to the value of the specific interfacial free en-
ergy a- which may be higher or lower than the border value
a-t- The aggregate instability of lyophobic systems increa-
ses with the decrease in particle size and with an increase
in their number per unit volume, i.e, with the increase of
Brown~s movement and the probability of effective collisions.
In lyophobic emulsions, further dispersion is impeded by the
increase of the reverse processes of coalescence. The dif-
ferences between lyophobic and lyophilic systems are especi-
ally pronounced for systems with liquid interfaces, i.e.
emulsions or semicolloids. These may be formed continuous-
ly from the lyophobic systems, type "oil in water", by in-
-active compcnen-1, like soap in suffi -

tent of the solid disperse Dhase is considerably increased
by stabilization, The high elasticity, i.e. the strongly
developed elastic after-action is a property of the coagu-
lation structure. The transitional colloidal systems easi-
ly form thixotropic coagulat-ion structures, i.e. gils, al-
ready at small concentrations of the disperse phase- The
mechanical properties of coagulation structures may be con-
trolled by increasing the degree of filling of the system
introducing stabilizers and coagulating agents, The part-
icles of the filler form a suspension which favors the de-
velopment of a three-dimensional structure, The electric
conductivity is influenced by the active filler, e.g. car-
bon black in rubber, and increases with the increase of the
potentials, The processes of destruction of solid bodies
and the foregbing deformation processes are very sensitive
to physical-chemical facto--s /~ef_ 307, The destruction pro-
cess, i-e. the appearance of new surfaces with correspond-
-ng surface enrgy, takes place at the expense of the elast-
I -
ic energy accumulated during the preceding deformation, Un-
der the same mechanical conditions of destruction, the new-
ly formed surface is larger in a surface-active medium than

ABSTRACT: The influence of hydrophilic organic surface-active substan-
ces of the sulfite-alcohol slops type on the properties of
cement, concrete, etc. is investigated. A Portland cement
suspension passes three phases during mixing: 1) The appear-
ance of a coagulation structure of the cement particles,
2) The appearance of a complex loose crystallization struc-
ture of hydro-aluminate, 3) The appearance o--F' a coagulation
structure of the initial cement particles and the newly
formed micro-crystals, Figure 1 shows the increase in the
plastic stability at various intervals of mixing in the pre-
sence of sulfite-alcohol sloDs SSB, The stability decrea-
ses due to a prolongation of the induction period of struc-
ture formation, then it increases rapidly due to 'he form-
ation of a hWdro-aluminatecrystallization structure. Figure
2 shows that the plastic stability increases with the quan-

obtained in phase 1 during mixing (Figure 3). Figure 4
shows the water-cement ratios necessary for the producticn
of an equally plastic cement, in the presence of SSB. The
greatest Dlasti-cizing effect, i.e. the greatest decrease of
the water-cement ratio is observed in phase 1 of the mixing,
This minimal water-cement ratio does not depend on the mine-
ralogical composition of the cement, The duration of phase
1 with various additions of SSB is given in Table 2 for the
two cement types AERM and KI'S. Various specimens of cement
with different additions of SSB were tested for res-~stance
after 3, 28, and 90 days, The results are given in Figures
5 and 6. The resistance curves for cement with preliminary
hydration (Figure 6) show a drop which begins at an earlier
stage than in the curves of phase I (Figure 5). The final
resistance of cement prepared by SSB i; always lower than
without SSB, if the %mater-cement ratio is constant (F--gure
7), if the initial plasticity is the sa:;-Ie (FiFure 8); the

TITLEt On the Surface Activity of Liquid Mletallic Coatings and
Their Influence on the Strength of Metals (0 poverkhnostnoy

One and the same coating of easily fusible metals diminishes
the strength of som-ci metals but exercises no influence on
other metals. On the other hand, also the behavior of one and
the sarae metal depends on the chemical nature of the metallic
coatinC~ The d,~-crease in strength can by no means be ascribed
to the dissolvin6 effect of the molten coating, nor need it
be connected with the selective effect on the grain boundaries.
Experimental data on the influence exercised by easily fusible
metal coatizi.-s upon the mechanical properties of metals are
divided into two distinctly separated groups: 1) The strength

is no such reduction of strength. A comparison of these data
with the diagrams for the fusibility of the corresponding
binary systems metal-coating shows that to the decrease of the
stren-,Yth of a solid metal under the influence of a liquid
coatinC there always corresponds the existence of a sufficiently
narrow but absolutely finite domain of the formation of a solid
solution. Corresponding to the complete lack of strength
reduction, there corresponds, in this diagram, a wide range
to which there corresponds the formation of a solid solution
of the metal coating in the investigated metal, Seen from this
point of view, the results obtained appear to be trivial. If,
however, the range characterizing the production of the solid
solution is so narrow that also the system metal coating is
ou"Iside this ran,-Ie, the deformation of the metal takes place
in the oresence of the liquid phase of the coating. The
reduction of the strength of the solid body (of the metal)
!itay be explained by the absorptive effect of the molten metal
coatin.g. In polymolecular transition layers to the film of

TITLE: New Trends of Colloid Chemistry (i'Tovyye puti razvitiya
kolloidnoy khimii)
PERIODICAL: Vestnik Akademii nauk SSSR, 1959, _Nr 1, PP 44-51 (USSR)
ABSTRACT: At present, colloid chemistry plays an especially important
part in political economy as it is a physical-chemical science
concerning substances of modern engineering~ It is of great
practical iMDortance that at present it is possible to carry
on uninterrupted transitions from lyophobic to lyophilic
systems. Thus, it is possible to obtain technically important
substances with the required structural-mechanical properties.
The theory of highly molecular substances and their solutions
has developed into an independent branch of colloid chemistry.
The vitality of modern colloid chemistry is proved by the
fact that it produces many new independent branches of science.
Further, the author describes the course of the 4th All-Union
Conference of Colloid Chemistry which took place in Tbilisi on
May 13-16, 1958. It was organized by the Otdeleniye khimiches-
kikh nauk Akademii nauk SSSR (section of Chemical Sciences,
Card 1/6 Academy of Sciences, USSR), in common with the Akademiya nank
New Trends of Colloid Chemistry SOV/30-59-1-5/57
Gruzinskoy SSR (Academy of Science, Gruzinskaya SSR). The
research work by M. Ye. Shishniash-~ili in.the field of sus-
pensions of betonite clay-types, as well as agrocolloids
- new organomineral preparations to increase soil fertility -
is mentioned. G. V. Tsitsishvili reported on adsorptive pro-
perties of natural and activated aluminum-silicate adsorptives,
in connection with their structure and their use as catalysts.
Ye. M. Nanobashvili spoke about radiation colloid chemistry.
The Conference was attended by about 400 reuresentatives of
nearly all the centers for colloid-chemical research at
schools, universities, and industrial enterprises of the
country, as well as by representatives from Bulgaria
(R. Kaishev, A. Sheludko), the German Democratic*Republic
(P. Tissen, G. Linde), Poland (A. Waksmundzki.,), and Czecho-
slovakia (K. Spurny*'-). About 160 reports were discussed. The
resolutions of the 2. Vsesoyuznoye soveshchaniye stroiteley
v Kremle (2nd All-Union Conference of Building Experts in the
Kremlin), which was dedicated to the development of the build-
ing material industry, were of great importance to the work of
the Conference. The author of this article reported on modern

in the kinetics of dispersion systems.
E. M. Natanson (Kiyev) reported on the present state of
research in the field of colloid metals.
A. D. Shpludko (Bulgaria) determined theoretically and
experimentally the regularities of synaeresis in foams.

of examination of water properties and structure of peat by
means of radioactive isotopes.
M. Ye. Shishniashvili considered questions of adsorption and
chemosorption of electrolytes in colloid dispersion systems.
B. V. Deryagin and his collaborators reported on the develop-
ment of the electrostatic stability theory as well as the
coagulation of dispersion systems, and on the theory of
formation and the properties of aerosols.
L. Ya. Kremnev, A. B. Taubman reported on the role of the
structural-mechanical barrier-as a factor of practical

as P. A. Rebinder showed it in his-investigations (Ref 1).
V. G. Levich theoretically showed that an increased viscosity
of the protective coverings of the stabilizer is sufficient to
prevent a -coagulation of particles.
M. M. Dubinin and his pupils dedicated a series of reports to
examinations in the field of structural characteristics.
A. N. Frumkin with collaborators examined new appearances of
adsorDtion in the theory of electrode processes.
B. A. Dogadkin, A. Ya. Korolev discussed questions of adsorp-
tive interaction of active fillers with p olymers, as well as
of the chemical modification of the surfaces of solid partic-
les (soot).
Ye. Ye. Segalova, P. A. Rebinder and collaborators reported on
the clarification of the process-of formation of crystallizat-
ion structure in the hardening of mineral binding agents.
G. M, Bartenev showed that the appearance of high elasticity
is connected with the formation of dispersion structure.
L. S. Palatnik (Kharlkov) examined the colloidal state of

Vir.ogradov and collaborators examined the properties of soap
solutions in connection with their structural peculiarities
and the theory of consistent lubricants.
The reports on questions of dispersion systems in polymers
showed the utility of a combination of problems of colloid
chemistry and the physical chemistry of polymers. The results
of the Conference indicate that, besides limited consultations
on individual scientific problems, comprehensive congresses
are also useful and necessary, uniting the investigators and
comprising the results of achievements in wide fields of
science. There is 1 Soviet reference-.

TITLE: On the Threshold of Three Sciences (Na etyke trekh nauk)
PERIODICAL: Tekhnika molodezhi, 1959, Nr 3, p 13 (USSR)
ABSTRACT: The author of this article, Academician Petr Aleksandrovich
Rebinder, has dedicated many years of his life to research work
in the field of physical and colloid chemistry. His principal
works deal with the investigation of surface layers on the bound-
ary surface between solids and liquids. Rebinder and his co-
operators opened a new neighboring field of science, named
physico-chemical mechanics. The new science makes it possible to
give desired properties to sAbstances produced on the basis of
polymers. In this article Rebinder writes that the near future
is unthinkable without new technical methods and new materials.
A large number of technical fields requires substances with
definite properties, such as space travelling, building trade,
aircraft construction, ship-building, the motor-vehicle and ma-
chine-building industry, etc. This indicates that metals will
lose their leading position as construction material, which
Card 1/2 does not mean, however, that they will be superfluous. They will

in many articles that people who have lost their way cannot go
straight on but move always in circles. That seems mysterious to
me. Answer: This phenomenon is not only observed in man. It was
found that blindfold dogs also move in circles and the same holds
for infusoria. That is, however, nothing mysterious as it results
from the geometrical asymmetry of the body and the irregular de-
velopment of muscles. 3) R- Haspilov, Veselinovo,Nikolayevskays

performance called looping is based on a known mechanical law.
The motorcycle or the car are pressed against the wall by the
centrifugal force, which is caused by the motion of a body on a
curved line at a certain minimum speed. The quantity of centri-
fugal force is computed by the formula F - mv2

TITLE. Influence of Low Melting-point Fused Metal on the
Mechanical Properties of Monocrystals of Higher Melting-
point Metals
PERIODICAL: Fizlka metallov i metallovedeniye, 1959, Vol 8, Nr 2,
pp 288 - 293 (USSR)
ABSTRACT: Single crystals of zinc (99.990/0 and cadmium (99.9pg%)
were used in fused tin and lead. Samples were deformed
at 10-150% per minute with a temperature constant to
+ 5 OC. The metallic medium (Sn or Pb) was deposited
in the sample electrolytically (thickness 5 0, which
was then placed in a tube with powdered graphite to
pre-vent oxidation, Figure 1 shows true stress-strain
dialgrams for pure zinc and zinc with a coating of tin.
At room temperature the influence of tin is small but
at hIgher temperatures tin causes a decrease in strength
and plasticity. The relation between temperature and
magnitude of the effect of tin is shown in Figure 2. The
sharp increase in effect at 300 - 4oo 0C is connected
Cardl/3 with an increase in solubility of zinc in -tin, The

character of the fracture also changes froin plastic in
air to brittle in tin. Lead-Ain m:Lxt-,Lres were also used.
The effect of pure lead is very slight but with increase
of tin content in the lead up to 200%, there is a sharp
decrease in strength and plasticity of zinc (Figure 3).
With fur-tkiex- Inc.-cease of tin content, the effect is much
slighter. it was shown that if zinz~ coated wita tin is
held in lead at 4oo OC for long priods, the stiength of
the zinc recovers (Figure 4). This shows the absent.~e of
any marked diffusion of tin in zinc,. A decrease in
plasticity and strength of cadmium in tin was also found
(Figures 5,6). The results on single crystals show that
the decrease in strength is not connected with any grain-
boundary effect.

TITLEs The Interaction at Ordinary Temperatures of Calcium Hydroxide
-'kith Sand of Various Degrees of Dispersity
_17ERIO-DiCAL: Koiloidnyy zhurnal, 1959, Vol XXI, 14'r 4, PP 442-448 (U33R)
AB_1*T_iACT: This is a study of the interaction of calcium hydroxide with
sand in aaueous solution. The exioeriments were carried out
with the aid of isotope Ca45, us-ed in the form of Ca*(OH)

The binding kinetics of the lime were studied with the chemi-
cal methods employed for the determination of free CaO. Object
of the irvestigation was sand (quartz sand) of the Vollsk de-

posit of different dispersi tY2 (specific surface S ). The dis-
values

experiments, which continued for 6 months, were carried out at
a temperature of 170 +_ 10 C. Figure I (graph) illustrates the

curves show that independently of the dispersity of the sand,
the binding process always consist's of two stages: 1) chemisor-
ption, which ends within one hour after the start of the inter-
actton, z.,.nd 2) a very long period of ohemical binding of CaO
at constant rates. The second process, evidently, is connected
with the formation of calcium hydrosilicate, the latter being
a new p'lase crystallized from the gradually formed supersatu-
rated solution. According to 1-13. Lrasill_.nikov, this process
will 'inally result in the full binding of CaG in the hydro-
I U
silicate, which corresponds to a final concentration of^-/0.006
t- 1, i.e. to a hydrolytic equilibrium of 'the calcium silicate
3/

ABSTRACT: A short report is first given on the present stage of the
problem and on earlier papers dealing with this subject.
The formation of a crystallization structure of reduced
strength and higher temperature is not due to the formation
of another compound, but to a modification of the conditions
of the crystallizing-out of the hydrate forming these com-
pounds. The authors investigated the kinetics of oversatura-
tions by employing the conductometric method at an optimum
rate of mixing (400 rpm). In order to prevent carbonization
of suspensions, all measurements were carried out in a nitro-
Card 1/4 gen atmosphere. In all sufficiently concentrated suspensions

a constant level of electric conductivity is established,
which corresponds to the maximum oversaturation. or to the
conditioned solubility of CA (an abbreviation used by the
authors for CaO.Al20 ). In suspensions of CA a constant
level of oversaturatlon is more quickly attained than in
tricalcium-aluminate suspensions, but it is still attained
much more slo7wly than in suspensions of semi-aaueous gypsum.
The rate at which maximum oversaturation isattained increases
considerably with an increa:3e of the concentration of the
susoensions. The existence of stable oversaturations which
are independent of the concentration of the suspension is
also indicated by the results obtained by the quantitative
determination of the concentrations of CaO and A12 03 of the
liquid phasip of the suspension,provided that electric con-
ductivity in this liquid phase has attained its maximum
value. The samples used for analysis were chosen from the
same suspen3i'bn in which electric conductivity had been
measured. The results obtained by analyses made it possible
not only to determine the existence of stable oversaturations

tatively. Accordin,-, to the results obtained by the present
paper CA is con,-,ruently solved: A concentration ratio of
CaO and Al 203 in tl~.n_ liquid phase of the suspension is equal
to 1, which corresponds to their ratio in the arid compound.
At the same time, the solubility of the hydrate 2 CaO.Al 0

aqu (C 2A.aqu) was determined, which was produced by.the
0
hydration of CA at 20 . It amounted to 0-4/0 9 C2 A per 1 1
of the solution, which is in good agreement with the data
0
found in publications (Ref 8). The concentration ratio of
CaO and Al 203 corresponds to the dicalcium aluminate
(CaO/Al 2030~ 2). The authors carried out similar experiments
also at 60 The curves for the variation of electric con--
ductivity also have a distinct maximum, which increases con-
siderably with an increase in concentration of the suspension,
and which becomes noticeable already after a shorter time.

saturation it is necessary considerably to reduce the rate
at which CA is dissolved, without hereby varying the experi-
mental temDerature. For this purpose a surface-active sub-
stance was0added to the suspension, viz. sulfite-alcohol-draff.
Also at 60 stable oversaturations occur by the hydration of
j
CA. The maximum value of concentrations does not depend on
the concentration of the suspensions, but it is attained more
quickly at higher concentrations. There are 3 figures, I table,

PERIODICAL: Doklady Akademii nauk SSSR, 1959, Vol 126, Nr 2,

ABSTRACT: In the course of the investigations discusued in the present
paper the aluminum soaps of naphthenic acids were used as
structure-forming additions. They form oleogels with peculiar
structurally mechanical properties. These properties of
oleogels depend on the molecular nature of the dispersive
medium and may be regulated by variation of these factors.
In this connection, the authors investigated the time-
-dependence of the viscosity of the gels of aluminum
naphthenate in hydrocarbon media and in concentrated
suspensions which are built up on the basis of such hydrocarbon
media. Ordinary technical suriace-hardened oxidized aluminum

as dispersive phase. The dispersion medium used was the
purified basic paraffin-naphthene fraction of the fuel
T - 1. The production of the aluminum soaps used for
structure-formation is briefly described. A diagram shows
the typical curves lg1L-1V for a 2% aluminum-naphthenate-Eel-
Here T, denotes viscosity and -6 - time. The introduction of
a solid phase increases initial viscosity considerably, but
without changina the character of its aging. Analogous
curves of aging are given for 2%- and 4%-gels of an
aluminum-naphthenalle of other composition. If benzene is
substituted for the paraffin-naphthene fraction, the initial
viscosity of the gel is reduced, but the viscosity of the
gel in the suspension undergoes practically no change for
the duration of one month. The eecrease of viscosity in the
oleogels of the aluminum-naphthenate and in the corresponding
suspensions is probably a consequence of the latent formation
of aggregates. There are 2 figures, 1 table, and 10 references,

ABSTRACT: The effect produced by acetone, ethyl alcoholy water, benzenes
triethanolamine and oleic acid upon the dispersion of quartz
sand was investigated. Crushing was carried out in a laboratory
vibration mill, and determination of the degree cf dispersioll
by measuring the specific surface by means of adsorption of
nitrogen at low temperatures a--cording to reference 14- Fig-
ures 1-4 and tables '1.and 2 show the experimental results. The
addition of liquids causes a considerable increase of the
specific surface in comparison to dry-grinding. The effect
produced by the individual liquids is about equal. This result
is explained by the fact that, in the case of dry grinding,
relatively solid particle complexes are produced, the tight
packing of which prevents nitrogen from penetrating, so that
a large part of the free'surface is eliminated. Additions of
Card 1/2 liouids cause a considerable extent, of desaggregation. As

of the liouid added. In water, a minimum occurs at an addition
of 2-30%, which is followed, as a result of further additions,
by a rapid increase of desaggregation. As shown by experiments,
the described phenomena are confined not only to quartz alone,
but in a different degree characteristic also of other solid
substances, such as corundum, and calcite. There are 4 figuresp

ABSTRACT: This article deals with the influence exercised by a thin li-
quid gallium film upon 'the mechanical and structural properties
of the single crystals of tin and upon their electrical con-
ductivity. Differently oriented single crystals of tin (degree
of purity 99.999 %, diameter 0.5 - 1 mm, length 10-25 mm) were
bred by the method of zone crystallization. The liquid me-
tallic gallium was mechanically applied to the surface of
the samples in a quantity of from tenths of a mill1gram to
5-10 mg. As in the case of Zn-Hg and other pairs mentioned al-
ready earlier, plasticity and strength of the single crystals
of tin decrease abruptly as soon as the gallium has been

strates the results obtained by measurement of the true tensicr-s
of the break resulting from an elongation of -.he gallium-
coated single crystals of tin at a constant velocity ofrJ20'Yo
min-1 as a function of the period of time passed since the
coating of the samples with gallium. The extreme relative pro-
longations increased by 50L/,,) (as a maxi:xuir. value') immediatel,-!--
after the samples had been coated with gallium. This perrentage
dropped to some per cent after the sampleshad beer, exposed

~o room temperature for 24 hours, and after some days _JI. was
only very small. The strength of single crystals coated with
gallium amounts to 1-5 kg/ m2 approximately iminediately after
the coating, and drops to 50 g 2 after 7-10 days. X-ray

Pictures taken before and after the coating showed that after
the coating the single crystal gradually decomposes into di-
stinctly disoriented blocks. After some days the initial sta2.ns
on the X-ray picture vanish almost completely, and the picture
resembles that of a polycrystalline metal. At a sufficient

latter on the single crystal of tin, this phenomenon extends
throughout the entire crystal volume. In the case of samples
oriented in such a manner that their original resistance is only
small (i.e. at large angles ), between the tet-ragonal
0 [00~
axis and the sample axis), resistance increases in the course
of time, while it gradually drops after the coating of samples
with high original resistance (if the tuetragonal axis is near
'the sample axis). Gallium (or gallium saturated with tin)
is a strong adsorbent for tin. During elongation in liquid
nitrogen the strength of samples coated with gallium really
increases as.compared to single crystals without coating. The
authors thank Professor V. I. Likhtman, who contributed to
a discussion of the results of this article. There are 4
figures, 2 tables, and 27 references, 26 of which are Soviet.

(USSR)
ABSTRACT: The authors investigated the process of CaO hydration on sus-
pensions which, besides CaO additionally contained 75'-,- CaCO
~
as inert filling medium, so that the ratio between water an
calcium was increased and structural development could be re-
tarded and heating of the samples could be reduced. The pure
2
CaCO
had a specific surface of 2000 cm
/g, determined by
3
Tovarov's apparatus. The strength of the suspensions was deter"
mined by means of a conical plastometer, and the rate of hydra -
tion was determined calorimetrically, Figure 1 and table 1 show
the course of the strength and hydration of suspensions with
a ratio between water and solid subs tarice 07/0)0f 0,4, 0,5, and 0.6,
Strength at first increases rapidly as a result of crystalliza-
tion of the main quantity of Ca(OH) V after which it decreases
rapidly and only rises gradually with 'W/S = 0.4 until the end

SOV/20-129-06-40/69
Features of Structural Crystallization in the Solidification of Calcium Oxide
by Hydration Figure 2 shows that the course of strength does not depend on
temperature conditions. As a cause of these variations of strerLcldip
the destruction of structure by the occurrence of internal
stresses during the growth of the crystals is given. The double
character of this process (increase of strength by crystal
growth, decrease by destruction of structure) causes the rise
and fall of the strength curve, which is particularly marked
with VI/S = 0.4. On the other hand, the dissolution of crystal-
lization contacts becomes effective only in the case of a large
W/S. The assumption of several Ca(OH) 2 modifications going over
into one another was refuted by thermograms and X-ray pictures.-
