Abstract
By this method of adding fly ash of equal amount in the mortar, making analysis including the decreasing water change、7d and 28d compressive strength as well as flexural strength. Results show that exists the optimum proportion of fly ash cement mortar, that is C：F：S：W=220：55：1410：275.On the basis of mixing only 20% fly ash and epoxy resin-polymer, doing analysis about the decreasing water change、7d compressive strength and flexural strength、application property. At the same time, this paper fits the regression equation which using the 7d compressive strength and flexural strength、decreasing water rate as the dependent variables, polymer cement ratio as the independent variable. More important is that the credibility of regression equation is much high.
