Strength and Durability Evaluation of Recycled Aggregate ...

Aggregate crushing value (ACV) provides an indication of the aggregate strength. Aggregate with lower ACV is recommended to ensure that the aggregate will be able to resist applied loads. The test was conducted on coarse aggregate of different grades. The ACV is calculated as the ratio between the weight passing sieve and the original weight.

Compressive Strength of Concrete Cubes Lab Test Procedure

Concrete Strength Overtime. So we can't predict the strength until the concrete comes to that stable state. Once it attains certain strength at 7 days, then we know (according to the table) only 9% of strength going to increase. So at sites, we do normally test concrete at this interval. If the concrete fails at 14 days, then we will reject that batching.
