A hydraulic inorganic composition belonging to high-content sulfate slag cements and comprising: (a) water-granulated blast furnace slag fine dust... about 80 parts by weight (b) light-burned anhydrous gypsum or hemihydrate... about 20 parts by weight (c) a mixtrue of at least one compound selected from the group consisting of NaOH, KOH, Ca(OH)2, CaO, Na2CO3, K2CO3 and CaCO3 and at least one compound selected from the group consisting of Mg(OH)2, Al(OH)3, MgO, Al2O3, NaCl, KCl, CaCl2, MgCl2, AlCl3, Na2SO4, K2SO4, MgSO4, Al(SO4)3 and MgCO3 with a mixing proportion by weight of 1 : 1-1 :6... 0.1-5.0 parts by weight. A hydrated and cured product of this composition is high-early strength, light in weight and high in mechanical strength with suffering no weathering. Upon curing, it undergoes volume expension. |
