PROBLEM TO BE SOLVED: To obtain a low-cost high strength material having high fire resistance, durability and designability. SOLUTION: A composition containing a potentially hydraulic material, a hardening exciter and water is kneaded with a crushed colored natural stone and optionally molded and the resulting kneaded material or molding excellent in fire resistance, designability, strength, physical properties and profitableness is cured and hardened. The potentially hydraulic material is preferably water granulated blast furnace slag or the slag and silica fume. Preferably, the composition further contains a water-soluble polymer.
