Research on Ultra-High Performance Concrete with Rice Husk Ash

摘要：

　　Tests were carried out on the properties of Ultra-High Performance Concrete (UHPC) by partially or completely replacing Silica Fume (SF) by Low-temperature Rice Husk Ash (L-RHA).The results show that the activity and adsorptive capacity of L-RHA is greater than SF; The compressive strength of UHPC is increased by both the filling effect and the secondary hydration effect for L-RHA,but only by the filling effect for SF.However,more than 10% dosage of L-RHA or SF reduces the early compressive strength of UHPC.The compressive strength of UHPC with two blends of L-RHA and SF with less than 10% dosage of each ingredient is higher than the one with only a blend of ingredient,L-RHA or SF.
