Integrated modifying zinc-containing additive for construction silicate compositions

Sodium silicate binders are a promising binder base for obtaining effective granular thermal insulation materials. Increasing water resistance, first of all, will expand the scope their application in construction. At same time, features modification sodium by compounds polyvalent metals have not been fully studied, interaction with which leads to formation hardly soluble silicates. The purpose this work was develop modifying complex based on zinc-containing compound - zinc acetate increase resistance and characteristics porous material. proposed additive is consisting an organic alcohol solvent. It shown that properties material can be controlled changing composition Qualitative quantitative dependences granules (strength, density, conductivity) type solution its content compositions obtained. concept mechanism sparingly complexes during aqueous-alcoholic solutions has developed. X-ray phase analysis showed system modified aqueous acetate, contrast completely amorphous state. We believe Zn2SiO4H2O, ZnSiO3 obtained research results made it possible determine rational heat-insulating increased operational functional (ρ = 200-280 kg / m 3 , λ 0.052-0.063 W (m °C), R 1.3-1.8 MPa, K r 0.89-0.92, 16- 18 %).
