ultrasonic pulse velocity (UPV) test is an in-situ, nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure or natural rock formation.
The hammer measures the rebound of a spring-loaded mass impacting against the surface of a sample. The test hammer hits the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment.
Concrete Rebar Locator. Rebar locators are used to find the position of steel reinforcement bars in concrete structures and to measure their concrete cover. Certain type of reinforcement such as glass fibre rebar, post-tension or pretension strand will require a Ground Penetrating Radar systems to locate correctly.
The half–cell potential test is the only corrosion monitoring technique standardized by ASTM. It is used to determine the probability of corrosion within the rebar in reinforced concrete structures.
