PURPOSE:To provide the method for manufacturing high strength inorganic multilayered molded matter, in which ply separation is hard to develop and which is employed as a building material and a civil engineering material. CONSTITUTION:Plys, which are made from an aqueous slurry composition prepared by homogeneously mixing 0.1-10 pts.wt. of polyvinyl alcohol-based polymer powder with 100 pts.wt. of a hydraulic compounded composition consisting of calcareous powder, silica powder and reinforcing fiber by paper making method, are laminated to one another in multilayers and compacted under pressure and finally cured by autoclaving at 120-200 deg.C. |
