•Aggregates are the important constituents in the concrete. Aggregates occupy 60 – 75 % of the volume of concrete. • Economy is not the only reason for using aggregates, aggregates give a higher volume stability and better durability to concrete. Cement paste alone has no such higher volume stability, strength and durability. • Aggregate properties significantly affect the workability ...
