The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value

Aggregate Crushing Value Apparatus 187 9999573785 187 . The aggregate crushing value acv test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod all parts of the apparatus are powder coated or galvanized steel, heat treated and

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).
