The article presents testing results of non-autoclave structural and heat-insulating foam concrete, made on the basis of astringents of different grades and with different fillers. It has been experimentally established that the best filler for foam concrete is microsilica due to its high specific surface area and low bulk density in comparison with the sand. The use of high-quality binders in foam concrete mixtures allows to increase not only the strength of foam concrete, but also the content of microsilica up to 70% with respect to mixtures at lower brands of Portland cement.
