The modern nanotechnology techniques allow receiving advanced composites of silicate matrix of thermal-moisture hardening the low-power technology today. A distinctive feature of geopolymer aerated composites is that their properties according to the basic physical and mechanical parameters exceed of the properties of the silicate matrix. Due to the implementation of a complex activation of highly mobile silicate concrete mixture, that is one of the technological features to obtain this type of composites, energy-saving modes of preparation were provided. The composites and products based on them are characterized by low density at high values of strength, water and crack resistance and heat capacity. The technological features of obtaining effective aerated composites on silica matrix of thermal-moisture hardening set out. The comparative analysis of the influence of the tripoli specific surface to the structuring of silicate matrix properties and porous composites modified of alkali containing additives were carried out. Based on this analysis the mechanism of formation of silicate matrix structure and properties was grounded and proposed. It is shown that the tripoli particles promoted “physical” seal structure of silicate matrix and the formation of capillaries’ discontinuous structure, by means of their own micro-porosity.
