Abstract
The article presents the effect of additives and water on the compressive strength and flexural strength of foam concrete after 28 days of normal hardening. The foam concrete mechanical properties are determined according to the GOST 10180-2012. The initial composition of the foam concrete mixture was calculated by the absolute volume method. As a result, the first-order regression equations are obtained. The compressive strength and flexural strength of foam concrete depended on the ratios x1 (В/(Ц+ДШ) and x3 (МК90/Ц), as well as on the expression of the image surface and the objective function for the regression equations. The optimal value was obtained: compressive strength = 42.14 MPa and flexural strength of 6.31 MPa.
