METHOD AND APPARATUS FOR PRODUCING HYDRAULIC INORGANIC COMPOSITE USING POROUS SUBSTANCE AS AGGREGATE OR REINFORCEMENT

WIPO Patent Application WO/1984/003063

A1

Method and apparatus for manufacturing a hydraulic inorganic composite formed by forcing a hydraulic inorganic hardening material into voids in a fibrous, granular, laminar, or massive porous substance. More particularly, the invention pertains to a method and apparatus for manufacturing a hydraulic inorganic composite wherein a hydraulic inorganic hardening material in which is mixed the porous substance is placed in a vacuum, the pressure is returned to substantially normal pressure, and subsequently the material is kneaded together before being removed to harden. The term "hydraulic inorganic hardening material" includes a cement, slag or wollastonite hydraulic inorganic hardening material. The hydraulic inorganic composite obtained by the invention has a high compressive strength and viscosity, and hardly cracks, and also has an excellent surface formability so has a wide applicability in various industrial fields including architecture and civil engineering.
