Crushing Strength Of Coarse Aggregate Test

Crushing test one of the model in which pavement material can fail is by crushing under compressive stress a test is standardized by is2386 partiv and used to determine the crushing strength of aggregates the aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load

Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete it also have a significant effect on the fresh concrete based on aggregates shape size texture grading and crushing type moreover it is proved that aggregates types has the severe effect on physicmechanical properties of concrete as aggregate covered

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
