The paper presents the analysis of the patent information about modification of composite materials by introducing functional complex additives and/-or nanoadditives. Inventions can be applied in building technologies in order to produce nanomodified composite materials on the basis of air and hydraulic binder substances, that will allow us to intensify considerably industrial production of nanomodified…
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…
