Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.

Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod.

Aggregate crushing Value =(W B /W A) × 100 Record. The mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. Safety & Precautions: Use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes & helmet during the time of test.

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).

3 2 Wet test 3.2.1 Preparation of the test sample The same as in 3.1.1. 3.2.2 Filling the cylinder Proceed as in 3.1.2. When the mass of the aggregate has been determined, the aggregate is immersed in water for 24 h. After soaking, take the aggregate out, allow to drain for 5 minutes, and then surface-dry it by rolling it in a damp cloth.
