PURPOSE:To obtain the title solidifying material which is excellent in executionability and a long-term strength, by adding a blast furnace slag to a specific portland cement. CONSTITUTION:100pts.wt. portland cement comprising 15-40wt.% 3CaO.SiO2, 45-65wt.% beta-2CaO.SiO2, 8-20wt.T 4CaO.Al2O3.Fe2O3 and 1-3wt.% gypsum and free of 3CaO.Al2O3 is mixed with 80-300pts.wt. blast furnace slag having a basicity of 1.7-1.9. The mixture is pulverized so as to have a particle size of 3,000-5,000cm<2>/g, to thereby obtain the title solidifying material. 120-250kg (in terms of solidifying material) solidifying slurry obtained by mixing the solidi fying material with 40-80wt.% water and optionally a water-reducing agent is mixed with 1m<3> soft soil. |
