Experimental Studies on the Influence of Gradation of Recycled Coarse Aggregates to the Strength of Self-Compacting Concrete

Abstract:

To make full use of waste clay bricks, we made recycled coarse aggregate by waste clay bricks and used it in self-compacting recycled concrete. In order to improve the utilization rate of recycled coarse aggregate and realize good workability, we adopted skeleton dense accumulation method. With the fitted curve method, we obtained an accumulation curve of recycled coarse aggregate with reasonable gradation. Under the same conditions, we made contrast test with the recycled coarse aggregate by different gradation way. Through contrast test, we found that the recycled concrete with skeleton dense accumulation method has better performance in strength and workability, and his method improved the utilization rate of the recycled coarse aggregate.
