FINAL REPORT EVALUATION OF CONCRETE …

each batch, and cylindrical and beam specimens were cast for determining the properties of the hardened concrete. In addition, cubes, 150 x 150 mm, were fabricated to measure UPV. The properties of the hardened concrete were determined using specimens tested at 7, 14, and 28 days. Prior to strength testing, the UPV of the concrete was determined.
