Abstract

The effects of fly ash, lime, alkali activator and styrene-acrylic emulsion on the compressive strength and flexural strength of fly ash cement were studied in this paper. The results show that the addition of fly ash can improve the workability of mortar, but it will reduce the strength of the material. Adding lime can effectively improve the strength of cementitious material. The strength of cementitious material increases with the increase of alkali activator dosage. The cementitious material with no more than 1% styrene-acrylic emulsion can effectively improve the strength of cementitious materials, which plays a toughening effect.
