摘要
PURPOSE:To surely obtain ultrahigh-strength hardened material of concrete by blending Portland cement with high-purity fumed silica, high-performance water reducing agent and water, molding and curing the blend in an autoclave. CONSTITUTION:400-600 kg/m3 ordinary Portland cement is mixed with 15-50% (outer percentage of cement) high-purity fumed silica, 2-8% (cement ratio) high- performance water reducing agent and 30-56% fine aggregate in 2.2-6.0 cement water ratio to give a mixture, which is molded and cured in an autoclave to give a hardened material. A method wherein 400-600kg/m3 ordinary Portland cement is blended with 15-60% (outer percentage of cement) high-purity fumed silica, fine aggregate (30-55%), coarse aggregate and primary water and then with 2-8% (cement ratio) high-performance water reducing agent and further secondary water in 2.2-6.0 cement water ratio is carried out as a method of surely obtaining the hardened material.
