The invention relates to the building materials industry, in particular, to the composition of the raw mix for the manufacture of non-autoclaved, steamed building products - transfer boards, blocks, building stones, etc.

The purpose of the invention is to increase the weight and decrease the bulk density.

Chemical composition of needles. enrichment factory are given in table 1,

The tails are sand with a modulus of grain size Mcr and a bulk weight of 1400 kg.

The chemical composition of volcanic slag is given in table 2.

Manufacturing techniques are as follows

Finely ground slag, tails, and the image of the proposed limits are; a, the holdings of the components are given in Table 3, and the physicomechanical indicators are given in Table 4.

The expected economic effect is 35 thousand rubles.

Claims (1)

10 claims Raw mix for the manufacture of cellular concrete, including finely ground slag, lime, gypsum, aluminum powder 15, waste from the mining and processing industry and water, so that it can be used to increase strength and reduce production weight, it contains as a message and gypsum mixed with a part of the Vrda 20 finely ground slag volcanic for 2 minutes, the rest of the water mixed slag fraction 0.01-0.1 mm, and as an aluminum powder and received waste mining and processing the suspension is poured into the mass and yes - the copper-molybdenum tails are more mixed for 2 minutes. Ready-made, production with a specific surface zobetonny solution poured into. 25 800-1000, with the following ratio: From the moment of rapid gas release of the quenching of components, wt.%: Volcanic slag The concrete mixture in the molds is subjected to vibration. Vibration is stopped in end of gas evolution. Hardening in the steam chamber at 90 ° С according to the mode: temperature rise up to 2 h, holding at 90 ° С - 6 h, temperature descent 2 h (10 h in total).
