The article considers influence of nature and amount of foaming agent on stability, multiplicity, strength and coefficient of foam use and also heat conductivity and strength of non autoclaved foam concrete.

The article considers a technical solution for the introduction of pozzolan additives into the cement after grinding clinker. Such additives are the fly ash of the CHP and ash from the ash dump. The use of ash in the composition of cement reduces its cost and energy intensity of its production

The article presents a theoretical calculation of the load-bearing capacity of out-of-center compressed box-section racks depending on the eccentricity and the amount of bending in the extreme fibers of the racks located in the middle third of their length

The static operation of the building frame elements formed from thin-walled open profiles located in a monolithic foam concrete array is considered. This arrangement increases the overall stability and fire resistance of the floor beams.

The article considers the growth of strength of foam concrete matrices: control and introduced into the composition of synthetic and protein foaming agent of a new generation. Shows the ratio of the strengths of matrices and the optimal time of hardening.
