The tests for Aggregate Crushing value and Aggregate Impact value were done according to BS 812 110 and BS 812 112 respectively The porosity n of aggregates was calculated using Eq 1 obtained from earlier studies This uses the data obtained from the specific gravity tests and it was assumed that the aggregates were fully saturated
