Abstract

PURPOSE:To increase strength-developability and strength-in-early-stadge at a low temp. by adding nitrite or nitrate salt of a alkali (earth) metal to hydrau lic composition contg. a fixed amt. of calcium aluminate mineral, and calcium silicate mineral and inorg. sulfate salt. CONSTITUTION:One or more kinds of salt selected among (D) nitrate or nitrite salt of alkali metal, or nitrate or nitrite salt of alkali earth metal is added by 0.1-15wt.% and mixed with the hydraulic composition blended with (A) >=13wt.% (amorphous) crystalline calcium aluminate mineral such as C3A, C12A7, CA, C3A3CaSO4, C3A3CaX2 (where A is Al2O3, C is CaO and X is halogen atom), preferably having C/A mol. ratio = 0.1-3, (B) e.g. 45-75pts.wt. calcium silicate mineral such as CS, C3S2, C2S, C3S (where S is SiO2) and (C) e.g. 8-25pts.wt. inorg. sulfate salt such as anhydrous calcium sulfate, calcium sulfate hemihydrate or dihydrate.
