The shelf carries them around until they drop on the opposite side of the drum, subjecting the aggregate to impact and crushing. Then, the aggregate is subjected to abrasion and grinding as the drum ...
The crushed aggregates (W2) is expressed as % of the total weight of sample (W1), which is the crushing value of the aggregate. Aggregate crushing value = (W1/W2)*100. Recommended Values: In aggregate crushing test, if aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate.
