Abstract

The article deals with the issues of regulation of water consumption of foam concrete mixtures. Theoretical substantiation of the possibility of using various mineral and chemical additives in the production of non-autoclave foam concrete is carried out. An experimental study of the flowability of nonautoclave foam concrete from mixtures of reduced water content is carried out. It is established that in a water-solid ratio equal to 0.38 the additive “Hemix Art-2” in the amount of 1.1 % of cement mass increases the fluidity of foam concrete mixture by 89%. It is obvious that with the use of the additive “Hemix Art-2” reduces the size of the bubbles of the involved air, which gives high plasticity of the foam concrete mixture.
