Fine aggregate used for the study was M-Sand and it was properly graded to give the minimum void ratio. Fine aggregate selected was free from clay, silt and chloride contamination. Specific gravity was determined as 2.62 Coarse Aggregate: It is the strongest and least porous component of concrete. Angular aggregates are preferred.
