Prediction of Compressive Strength of Reinforced Concrete Structural Elements by Using Combined Non-Destructive Tests

This research is devoted to investigate relationship between both Ultrasonic Pulse Velocity and Rebound Number (Hammer Test) with cube compressive strength also study the effect of steel reinforcement on these relationships. A was carried out 32 scale model reinforced concrete elements. Non destructive testing campaign (mainly ultrasonic rebound hammer tests) made same About 72 cubes (15 X 15 X15) were taken from mixes check strength.. Data analyzed.Include possible correlations non (NDT) (DT) Statistical approach used for this purpose. new relationships obtained results given.
