PURPOSE:To obtain satisfactory strength of a product even when waste such as slag is used, by adding a metallic salt for increasing the solubility of calcium to a hydraulic blend consisting of cement, silica and blast furnace slag in a specified blending ratio. CONSTITUTION:A metallic salt for increasing the solubility of calcium in cement is added to a hydraulic blend consisting of cement, silica and blast furnace slag in (6:3:1)-(3:3:4) blending ratio by 1-8wt.% of the amt. of the starting material to obtain a cement blend for an autoclave. The metallic salt is barium chloride or calcium chloride. When the blend is mixed with reinforcing fibers, aggregate, water, etc., molded and cured in an autoclave, a reaction is activated by the action of the metallic salt and a high strength product can be obtd. |
