PURPOSE:To obtain the subject composition having excellent selfleveling property and capable of easily getting high strength by compounding a specific clinker powder with gypsum containing insoluble gypsum anhydride, S03- containing cement and a dispersing agent. CONSTITUTION:A clinker powder (A) having a Blanie value of 3,300-4,000cm<2>/g and composed of <=5wt.% of 3CaO.Al2O3, 8-12wt.% in total of 3CaO.Al2O3 and 4CaO.Al2O3.Fe2O3 solid solution and the remaining part of 3CaO.SiO2 and 2CaO.SiO2 is obtained by selecting from low-heat Portland cement clinker, etc. The objective fluid hydraulic composition is produced by compounding the component A with (B) gypsum containing >=50wt.% of insoluble gypsum anhydride, (C) cement containing 2-5wt.% of SO3 in the cement and (D) a dispersing agent. |
