| Abstract: | In order to improve its activity,a composite optimization treatment was given to the flyash based on its mineral composition and activity mechanism.The test suggests that the sand grout for cementitious materials can attain the standard of cement No 42.5 in strength when large amount of flyash(50 percent) is added in the production.This finding provides experiment data and utilization of vast amount of flyash. |

| Keywords: | fly ash activity optimization configuration characteristic cementitious capability |
