The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS
Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road construction is expressed by numerical indexMay 18 2018 The mean of compressive strength achieved by this specimen is used to determine actual strength of the batch Procedure for Compressive strength of concrete or Cube test Place the prepared concrete mix in the steel cube mould for casting Once it sets After 24 hours remove the concrete cube from the mould
