PROBLEM TO BE SOLVED: To produce an inorganic composition, capable of reducing the weight by reducing the wall thickness due to a high strength and providing an inorganic hardened product, improved in executability and having high abrasion resistance and provide a method for producing a highly abrasion-resistant inorganic hardened product. SOLUTION: This inorganic composition comprises (A) 100 pts.wt. SiO2 -Al2 O3 - based powder, (B) 1-300 pts.wt. alkali metallic silicate, (C) 10-1000 pts.wt. water and (D) at least one or more high-hardness grains selected from the group consisting of 1-100 pts.wt. grains, comprising oxide-based grains having >7 Mohs hardness and containing >=70wt.% thereof having 5-300μm grain diameter and/or 1-100 pts.wt. nonoxide-based grains having >7 Mohs hardness and containing >=70wt.% thereof having 5-300μm grain diameter. |
