Multiple influence of silica-containing component of the chemo-biogenic origin on the structure and properties of composites on silicate matrix
A distinctive feature of the silicate matrix composites unlike silicate autoclaved concrete is that they are made on the basis of the ternary complex activated silicate concrete mixture modified by alkali and mineral additives, and harden at 85 °C and standard atmospheric pressure. Due to the implementation of a complete 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. Now there is clear idea about the functional role and impact on the structure and properties of silica-containing components chemo-biogenic genesis, which were previously used either as active mineral additives or fillers. The comparative analysis of the influence of the tripoli specific surface to the restructuring and silicate matrix properties and porous composites modified of alkali containing additives other 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.
