“…Developed by the authors the complex activation includes the continuous loop of the different types and methods of activation: mechanical, chemical and thermal [6,8,9,10]. Each type of activation is accompanied by effects which create the conditions for the possibility of subsequent type of activation.…”

“…As nanotechnology reception the mechanochemical activation reduces the viscosity of 3 or more dispersed system containing lime [6,8,9,10,11]. This effect of viscosity reducing was used to compensate the increased water demand of the mixture introducing the composite porous opal-cristobalite rocks and using the activation of the binder together with the fine aggregate.…”

Abstract. The bases of silicate materials' manufacture of non-autoclave hardening are developed. The realisation opportunity of technological decision complex of using of mineral substances' structure in silicate materials' manufacture of non-autoclave hardening and wall's products on their basis is theoretically proved and practically confirmed. The complex activation of mixture with water materials, as slip, defined the transition from autoclave treatment to thermo-moisture one of silicate materials. The possibility of the practical realization of structure mineral substances' reserve for the energy consumption of silicate material production are proved experimentally. The optimization of the composition and the hardening conditions in the conditions of thermo-moisture treatment on the basis of experimentally-statistical modelling ensured the receipt of materials with the required properties. The analysis connection between hardening conditions and contents has been fulfilled on experimentalstatistic models. The changing of silicate materials' properties under the influence of inorganic modifier' surface, of hardening conditions and content of gypsum addition have been estimated. Correlation analysis allows to receive new information about the influence of the contents and the hardening conditions on a degree of interrelation between the structure and the properties of building materials. Optimal compositions and the regimes of hardening are recommended for the receipt of wall's articles of a different purpose.

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.
