| Abstract: | By means of activator,a kind of large gangue content cement was obtained,which gangue content is 60% and R 28 is up to 49.6MPa.The physical property such as normal consistency water demand,setting time and soundness of cement can meet the standard.The harden cement has lower porosity of 0.0413cm 3/g and lower hydrate heat which is 253kJ/kg. |

| Keywords: | large gangue content cement activator physical and mechanics property porosity hydrate heat |
