Title of the articleLoad-bearing structural insulating material with granulated filler for earthquake resistant building
Abstract.Using of pellets, derived from natural materials and amorphous silica-alkali metal hydroxides as placeholders for silicate concrete, produces wall materials of low density and thermal conductivity. They have a closed porosity and fuzzy interface between the filler and the matrix can be used in earthquake-resistant construction, and greatly simplify the weight of building structures without reducing their insulating and strength characteristics. Due to the high adhesion to mortar recommended their use in earthquake engineering, including in the Far North. It should be noted the low thermal conductivity of the resulting silicate material and relatively high flexural strength. Sodium silicates released during autoclaving of the proposed aggregate impregnated matrix connecting Portland, heal microdefects and fugitive pore silicate material, doubles the values of the structural quality of building products. Due to the introduction of the developed aggregate in the silicate material formed organized porosity, pore act as shock absorbers: it do not develop the longitudinal and transverse cracks, which would produce a solid matrix. In general, the average density of the material is significantly reduced.
Keywords.Silicate material, active granular filler, thermal conductivity, walling material, earthquake resistant building.
