agg crushing value nigeria



Pavement materials Aggregates

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.
