| Abstract: | This paper selects four different qualities of fly ashes in Gansu province and,has tested water-reducing ratio and strength of fly ashes in mortars.The results show that the qualities of fly ashes take a great effect on water-reduction and strength in mortars,FA1 and FA2 are better than FA3 and FA4 on water-reduction and strength in mortars.Compressive strength of cement mortar and water-reducing ratio have a good negative linear correlation.The better the fly ash water-reducing property,the greater impact ... |
