Study on Compressive Strength of Self-Compacting Concrete (SCC) Based on Fly Ash
Fly ash (FA) has a good effect on the fluidity and strength of self-compacting concrete (SCC). The experimental research method was adopted, equipped with C35 self-compacting concrete, w/c =0.4 and FA content a =0%∼40%. The compressive strength of SCC was studied for T=3d, 7d, 14d, 28d, 60d. It is f...
