getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.

Disparity in research findings on parent concrete

The aggregate crushing value of C20/25, which is 5-year-old concrete aggregate, which is the highest value in this test, was 34%, 25% for C55/67 material, and 18% for natural aggregates. This demonstrates that the aggregate crushing values of natural aggregates and recycled aggregates are equivalent at an enhanced parent …
