Initially, it is prepared to stand by joint grinding of granulated phosphorus slag, secondary cement dust and cement, to a specific surface of 3000 cMvr. Then take the calculated amount in the ground and ground sand with a specific surface of 1800-2000 cMVr and mix thoroughly. A calculated amount of a solution of sodium sulfate and aluminum powder is added to the dry mixture. Here, the water-solid ratio is 0.42. The prepared raw mixture is placed in a 10x10x10 cm form. After removing the hump, the samples are subjected to steaming at 2 + 10 + 2 hours with steaming or at 2 + 8 + 2 hours at 174 ° C. The strength characteristics of the prototype and the proposed invention are given in the table.
