.1 Ultrasonic Pulse Velocity (UPV) Test-It measures time of travel of ultrasonic pulse passing through the concrete. This method is ideal tool whether concrete is uniform and homogenous, pulse velocity readings are generally indicative of quality of concrete.
2. Rebound Hammer Test-This method provide compressive strength of concrete.
3. Half Cell Potential Test-To evaluate potential of concrete in promoting corrosion activity of reinforcement.
4. Cover meter test-This test is for locating mapping and thickness gauging of cover provided for embedded rebars in concrete.
5. Pullout test-This test is conducted on hardened concrete, this is done by LOK test and CAPO test, its results closely correlate to the compressive strength of concrete.
