Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 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.

The impact crusher is a highly efficient coarse, medium and fine crusher for mediumhard and softer rocks. Whether in a quarry, mining or Construction waste recycling, the impact crusher can efficiently crush the stone, so that the particle shape, particle size distribution and cleanliness are in line with the strict standards of concrete and asphalt aggregate.
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: The Constructor, Civil Engineering Home)
