Two concretes mix designs were investigated with the targeted compressive strength of 25 MPa and 40 MPa at 28 days. The fine aggregates were used in the form of uncrushed river sand with a fineness modulus of 2.7 and specific gravity of 2.5. The aggregates were oven dried for over 24 h prior to using to control the water content within batches.
