Abstract

1537501 Cementitious composition MATSUSHITA ELECTRIC WORKS Ltd 24 Dec 1975 [28 Dec 1974 27 Feb 1975] 52900/75 Heading C3N [Also in Divisions C1 and D2] A composition comprises a cement, which liberates calcium hydroxide upon hydroxide, glass fibres, and at least one of (a) 0À25 to 1-0 mole active alumina per 3 moles of Ca(OH) 2 liberated (b) 0À5 to 2À0 moles aluminium hydroxide per 3 moles Ca(OH) 2 liberated (c) 0À2 to 1À2 moles amorphous silica per mole Ca(OH) 2 liberated and (d) 0À2 to 1À2 moles crystalline silica (mean particle size below 50 microns) per mole Ca(OH) 2 liberated. Compound which form Al(OH) 3 in the reaction system such as aluminium chloride may be used. The composition may contain a catalyst selected from alkali metal halides, alkaline earth metal halides, alkali metal carbonates, alkaline earth metal carbonates and water glass. The composition may also contain water content decreasing agents, air-entraining agents, deforming agents, foaming agents, expansive agents, adhesive additives, mineral powders, lightweight aggregates, waterproofing agents, pigments, mineral fibres, synthetic fibres, natural fibres, sand, gravel and synthetic resin. Setting and hardening can be at elevated temperature in a CO 2 containing atmosphere. Shaping may comprise a paper manufacturing method, casting, spray dehydration and compression moulding.
