| Abstract: | Effects of coal gangue on the mechanical properties of cement mortars and their chemical stability exposed to NH_4NO_3 solution were investigated in this paper.Results show that the strength of cement mortar is reduced with increase in the amount of coal gangue,but the pore structure and chemical stability of cement mortar is obviously improved by adding coal gangue. |

| Keywords: | coal gangue mortar strength chemical stability pore structure |
