Aggregate Crushing Value ACV Testing Procedure All Aggregate Crushing Value Test Determine Aggregate

Jan 04 32 Procedure of testing Aggregate Crushing Value ACV 1 Make a sieve analysis and get sufficient amount of aggregate by using 140 mm passing sieve and mm retained sieve 2 After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm 3Coarse 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
