CONSTITUTION: A high strength and fast hardening cement composite is provided to use in requiring emergency for a structure mending by using mixed cement containing calcium sulfoaluminate(3CaO 3Al2O3 CaSO4) and calcium silicate(2CaO SiO2)as main ingredients, and 35-50 wt.% of Hauyne clinker, 25-35 wt.% of Portland cement, 10-25 wt.% of anhydrous plaster and 5-10 wt.% of calcium hydroxide. The amount of 100 weight of the mixed cement is mixed with 0.1-1 weight of an assimilative agent and 0.1-1 weight of citric acid as a setting retarder. The high strength and fast hardening cement composite has excellent compressed strength in initial and final strength.
