Aggregate crushing value of aggregates with cement

An aggregate specimen is compacted into a steel cylinder fitted with a nofriction 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).
