    Aug 22, 2021 i. Crushing Value. The crushing value gives the resistance of a coarse aggregate to crushing under the application of compressive load. j. Deleterious Materials. Coarse aggregate should be free from deleterious materials such as clay, silt, dust, salt contamination, organic materials, etc. because these materials weaken the bond. k. Surface Water

    Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates
