The article deals with the capability of non-autoclaved foamed concrete quality improvement by entrained mixture additives infusion into structure, which are the active centres of the basic phases magnesia stone crystal yielding. Two factor experiment of optimal concentration proportioning was conducted and finished by plotting graphic diagrams. The paper studies the basic mechanical characteristics of designed foamed concrete while conducting the experiment. We revealed a positive effect of crystallizing centres infusion on the speed of taking bearing power and resistance of modifying mixture. The paper studies the phase structure of hardened magnesia stone and determined the effect of the basic structure-forming minerals composition on the strength characteristics of foamed concrete on its foundation, along with the exploitation samples characteristics of optimized composition.
