Use of a new generation superplasticizer with the properties of non-autoclaved foam concrete

The article presents the results of experimental studies to study the effect on the physical and mechanical properties of foam concrete of the amount of microsilica microsilica of Uzmetkombinat JSC and polycarboxylate superplasticizer VESTA HPR 801 introduced into the composition as a mineral filler. It was revealed  that with an increase in the amount of microsilica in the composition of foam concrete to a certain value, the compressive strength of the material first decreases, and then sharply increases. In this regard, by analyzing the regression equation, the optimal values of the prescription indicators of the foam concrete composition were substantiated.
