The concrete compressive strength for the ready-mix concrete varies from 25 MPa to 62 MPa.The slump was 250 mm to produce high performance concrete for all the specimens.Twenty-four standard cylinders (150 x 300 mm) were cast with each pour and tested frequently to monitor concrete strength with age.The compressive strength of the concrete used in each specimen is shown in Table 1.The nominal maximum size of the coarse aggregate was 10 mm diameter.
