ca-..wed a reduction in the amount of A1203 relative to that of mullite. It
is possible to obtain a mullite refractory suitable for blast-furnace use by
the addition of 2,10 MnO (4% MnSbO to a charge consisting of clays and kaolins
with calcined alumina in proportions that will insure a complete mullite re-
fractory by firing at 15000 to 16000c. The MnO will not favor carbon de-
position within the brick. B. Z. K.

19480 May-iJune, p 193&)* Results of tests on an unfired chrome- .00
dolomite refractory showed that it may replace magnesite and 4500
ohrome-imagnesite bricks in steel furnace*. A ohrame-dolomito
refractory in the form of a astal-asped tube was tested in the
and wall of a 40-ton open-hearth furnace operatinr, on oil. At zoo
the point in question silica and other refractories withstood
from 40 to 60 melts, whereas the chrome-dolomito refractory with-
stood 370 molts. In the back wall of an open-hearth furnace, COO

disintegration of chromie-dolomito bricks and magnesite bricks
44iju was Identical. It is concluded that the use of unfired chrome -
dolomite bricks effects big savings in fuel and cuts dawn the
'0 oonovieption of magnesite.

Since the composition of commercial portlemd cement
is very complicated, studies are first made of cements
containing =Iv one,, then t-wo, three and so on, off the
main oxides making up ordinary cement. The chemical
equation relating CaO and the other oxides 21T16

(7), 9-11j abstr. In Chem. Abstr., 1949, vol. 43, 1938). Ash from
power station boilers in combination *ith other substances was tested
for its suitability as a bonding material. For these tests the ash
was mixed with anhydrite or with anhydrite and line. In addition was
also tested a mixture of cement and anhydrite. The mixtures of
anhydrite and ash were weaker than anhydrite alone. The addition of
up to 10% of lime and keeping the ash content at not over 10% improved
the resistance of the mixture.

Subject cement speeds up hydration of calcium sulfate
and increases its hardness and water resistance.
Hardening of semihydrous and anhydrous cements goes
on best in air media, and. takes approximately 7 days.
Humid climates cause setting to take place in about
28 days. Cements containing gypsum set faster than-
ordinary cements. Submitted 28 War 1947.

BUDMIXOV, P. P.
Budnikov, P. P. and Zhukovskaia, S. S., The method of determination of silicon by
volume in cast iron and steel. P. 959
The checking of the volume method of determining silicon in bakelite vessels
on standvrd sample gave satisfactory results. It was interesting to apply this
method to th,, quick-cutting instruments and other kinds of steel containing tungsten,
the presence of which complicates the determination of silicon by the weight method.

S.S.R. When the gypsum content is less than 30%, it is possible to obtain
almost complete liberation of S03 by heating at UOOoC. for 0-5 to 1 hr.;
complete expulsion of S03 occurs from the melt. Gypsum clay having a low
