Abstract
Abstract A self-hardening composition consists essentially of 3-5% by weight of an alkaline earth metal chloride, 0.5-1.5% by weight of calcium metasilicate, 0.5-1.5% by weight of sodium fluorosilicate, 30-40% by weight of sodium silicate, 0.02-0.04% by weight of aluminum silicate clay and water. Composites made therefrom can include expanded aggregate material and/or reinforcing fibers, as extenders, or to impart control over the open curing time to preset requirements.
