Изобретение относитс  к составам газобетонных смесей и .может быть использовано в нромышленности строительных материалов.The invention relates to compositions of aerated concrete mixtures and may be used in the building materials industry.

Известны газобетонные смеси, содержащие цемент, известь-пушонку, алюминиевую пудру и воду.Known aerated concrete mixtures containing cement, lime-fluff, aluminum powder and water.

Цель изобретени  - интенсификаци  процессов порообразовани  и схватывани .The purpose of the invention is to intensify the processes of pore formation and setting.

Поставленна  цель достигаетс  тем, что смесь дополнительно содержит глинисто-карбонатный шлам в количесчве 0,34-0,48 от веса цемеита.The goal is achieved by the fact that the mixture additionally contains clay-carbonate sludge in an amount of 0.34-0.48 by weight of cemeite.

Например, може1 быть использован глиписто-карбонатпый П1лам,  вл ющийс  отходом калийиого производства.For example, glypite-carbonate P1lam, which is a waste product of potash production, can be used.

Глинисто-карбонатный шлам представл ет собой пульпу, состо щую из перастворимого остатка (Н.О.) и жидкой фазы - раствора хлористых солей в воде.Clay-carbonate sludge is a pulp consisting of an soluble residue (N.O.) and a liquid phase — a solution of chloride salts in water.

и рН жидкой фазы6,5-7,5and pH of the liquid phase6,5-7,5

Шлам может быть вз т непосредствеппо из производства, а может быть использован шлам, отмытый от хлоридов с остаточным их содержанием 1-3%.Sludge can be taken directly from production, and sludge washed from chlorides with a residual content of 1-3% can be used.

Одной из особенностей шлама  вл етс  высока  водоудерживаюша  способность, обу2One of the features of the sludge is a high water retention capacity,

словленна  его полидисперсным строением. Минералы шла.ма имеют пониженную склонность к пабуханию и ск.леиваиию между собой . Гранулометрический состав щлама:sloped by its polydisperse structure. Sla.ma minerals have a reduced tendency to pabuhaniyu and sk.leivaiyu among themselves. Grain size distribution:

Глинисто-карбонатный шлам содержит большое количество мелких фракций (10- 1 мк и менее 1 .мк 60-90%), вследствии чего может быть при.менен без размола.Clay-carbonate sludge contains a large amount of fine fractions (10-1 microns and less than 1 μm 60-90%), as a result of which it can be applied without grinding.

За счет наличи  хлорисгых солей в шламе интенсифицируютс  процессы порообразовани  и схватывани  газобетона.Due to the presence of chlorine salts in the sludge, the processes of pore formation and setting of aerated concrete are intensified.

Приготовление газобетона ведут без нодогрева составл ющих материалов при температуре 10-15°С.The preparation of aerated concrete is carried out without nodogreva component materials at a temperature of 10-15 ° C.
