Aggregate Crushing Value Test Determine Aggregate

17/05/2019· Take the aggregate out of the cylinder and sieve them through a 2.36 mm IS sieve. Weight this fraction passing through it to an accuracy of 0.1 gm. This fraction is a quantity of the loss of material due to crushing. Note down the observations in the proforma then compute the aggregate crushing value.
