Abstract The objective of this study is to investigate and evaluate the effect of fine aggregates aggregate size smaller than or equal to 236 mm on the compressive strength and Aggregate size and shape vary too The size which can range anywhere from 3/8 inch to 2 inches or more in diameter largely determines the depth of exposure
