<p>PROBLEM TO BE SOLVED: To improve both mechanical properties and surface smoothness of the inorganic formed body by using an inorganic hardenable composition which has high water-filtration properties and enables a high yield of the inorganic formed body produced from it. SOLUTION: This hardenable composition consists of an inorganic hardenable material and reinforcing fiber. In this composition, as the reinforcing fiber, a combination of fiber (A) consisting of finely fibrillation cellulose that has 0.01 to 1μm average fiber diameter, 100 to 1,000μm average fiber length and an average axial ratio (L/D) of 2,000 to 100,000 and fiber (B) which is at least one kind of fiber selected from fiber (B1 ) consisting of fibrillation pulp fiber that has a 5 to 50μm average fiber diameter and a 1 to 5mm average fiber length and fiber (B2 ) consisting of organic synthetic fiber or inorganic fiber, that has 5 to 50μm average fiber diameter and 1 to 10mm average fiber length, is used. A slurry of the hardenable composition is subjected to papermaking and hardening to produce the objective inorganic formed body (cement formed body).</p> |
