Foam stabilization by nanosized additives is proposed to use as the means for increasing the quality of non-autoclave foam concretes. Sols of silicic acid and iron hydroxide were chosen to be such additives. The paper shows that nanosized particles make it possible not only to increase the resistance of the foam itself and foam concrete mix but also to use cement hardening activators without foam destruction.
