The IS limits for above tests are Aggregate Crushing value Aggregate Impact value and Aggregate abrasion value. 5. Aggregate Absorption. Aggregate absorption is used for applying a correction factor for aggregates in dry condition and determining water demand for concrete in

Aggregate Crushing Value Of Aggregates With Cement

An aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger. The specimen is then loaded via the plunger. The load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value ACV.
