Composition for forming inorganic hardened products and process for producing inorganic hardened products using the same

摘要

A composition for forming inorganic hardened products, which comprises a precursor for forming TSH, gypsum and a cement material selected from the group consisting of Portland cement, blast furnace slag and a mixture thereof, the amount of each ingredient satisfying the following relations by weight: 1/0.2>TSH/Cement material>1/5 1/0.1>Precursor/Gypsum>1/1 wherein TSH is the theoretical amount produced by the reaction of the TSH precursor and gypsum, and a process for producing inorganic hardened products from the composition.
