Research on the Experiment of Self-Leveling Concrete with Large Content of Fly Ash

In the research, self-leveling concrete with large content of fly ash is gotten, which compound super plasticizer and retarder. Adding plasticizer into concrete solves a problem of extensibility losing. Thickener mixed enhances homogeneous and steady of concrete heavily. Self-leveling concrete slump is 245mm, its fluidity is 630mm and its compressive strength is 44.5MPa(28d). Fly ash content of self-leveling concrete accounts for 30 percent of cement, fly ash mixed not only increases its fluidity, making durability better, saving costs and but attains double effect in technology and economy.
