This study examines the mechanical and durability properties of five different concrete mixes using the construction and demolition waste as partial replacement of coarse aggregate. In the concrete mixes, a constant water–cement (w/c) ratio of 0.43 was used. In contrast, the natural coarse aggregates were replaced by recycled coarse …

The specifications of the aggregate samples are kept similar for all of these three test procedures. The result indicates a strong correlation of Light compaction values (LCV) with Aggregate crushing values (ACV) and Aggregate Impact Values (AIV). The R2 values for the relationship was found to be more than 0.9 for both these relationships.
