Originální abstrakt

This work deals with the basics and possibilities of preparation non-bearing, heatinsulating material based on autoclaved aerated concrete. The ultra-low volume weight (under 200 kg/m3) and sufficient compressive strength is achieved using standard industrial technology. The low volume weight and therefore low heat conductivity can be reached due to highly porous structure. Such a material can be prepared by foaming very fine material powder like silica fume and very finely ground sand. Unfortunately, foams consisting of fine inorganic hydrophilic particles are highly unstable. Therefore it is necessary to use an effective stabilization mechanism. In this work the stabilization mechanism is based on addition of small amount of water-soluble organic admixtures.
