METHOD OF PRODUCING SILICATE-SODIUM COMPOSITE BINDER FOR HEAT-RESISTANT NON-CEMENT CONCRETE

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to construction materials, specifically to production of silicate-sodium composite binders for making heat-resistant non-cement unfired concrete. In the method of producing silicate-sodium composite binder for heat-resistant non-cement concrete, involving mixing fine-grained refractory filler and sodium silicate, hydrated fine-grained sodium silicate with specific surface area of 2500 to 300 cm2/g is converted to nanoparticles through dehydration dispersion steaming at temperature ranging from 200 to 600C with outlet into a bubbler with silicon resin until saturation of the resin with nanoparticles to 20% of the mass of resin. ^ EFFECT: increased compression strength and operating temperature of objects.
