Abstract

A gas-concrete mixture of non-autoclave curing consists of portland cement, sand as a filler, aluminum powder, water and complex additive, containing a mixture of caustic soda and carboxymethylcellulose. The complex additive comprises grounded lime and sodium sulphate, and as the filler ungrounded sand is used.

The disadvantage of the specified composition of the mixture is that it does not contain a complex additive of ground lime, and such a mixture is not suitable for the production of sodium sulfate-free. and with the complex interaction of porous concrete, which is obtained by the method together with caustic soda, it contributes to the intensification of the kinetics of the vertical formation of massifs. gas formation in the mixture. Due to the increase in the temperature of the array and the presence of sodium sulfate, there is a mixture that is closest to the mixture (USSR Copyright 481564, the process of growth of plastic mics accelerates) , properties of the formed porous massif, which usually consists of Portland cement, fine-grained production conditions. A complex combination of used sand, aluminum powder and a complex addition in the composition of the carboxyl methyl cellulose additive, which contains a mixture of caustic soda and carboxyl and caustic soda, ensures the production of homogeneous methyl cellulose, water, with the following density of the formed mass of aerated concrete and the ratio of components (wt. 9b ): excludes his sitting. The use of non-fine Portland cement 28-33 sand and the non-autoclave production technology lead to a reduction in costs in the structure of the bulk of the cement with the following ratio of the cost of the building material. ponents, mass. 9u:

As a result of the comprehensive studies of the swelling and growth of the plastic strength of denim, the optimal composition of the aerated concrete mixture was selected.

As can be seen from the table, as a result of the use of different densities of aerated concrete products -

additives in the composition of the aerated concrete mixture in the amount increases the strength of the samples under compression by 20-25 2.2-28 9o from the mass of the binder, twice (compared with the control composition) the process is accelerated. The technology for the production of plastic the strength of the formed drawing of effective wall products from aerated concrete gray to cutting the "bump" and cutting the non-autoclaved hardening material due to its use in wall blocks.

Such an effect provides an increase in the composition of the complex additive does not undergo a decrease in the productivity of the equipment, and, accordingly, changes, and is quite easily transformed into a shortening of the payback period of capital investments in the conditions of existing construction material production.
