There is a general trend that RCA has higher values for crushing and L.A. abrasion than NA, meaning when the aggregate is contained and crushed or impacted by steel balls in the L.A. abrasion test …

Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size. Fine aggregate

the laboratory density figures to compensate for the effect of the oversize particles. The formula that has been used in ia assumes that the minus No. 4 material is able to maintain its maximum laboratory density constant, much as though this material were a fluid, and that coarse aggregate particles merely displace a portion of the fine 22
