16 test methods for physical and mechanical properties of concrete
Concrete is the most widely used building material, and its quality is closely related to the safety of building structures. Various countries have done a lot of research in the measurement and evaluation of concrete performance, and have formulated corresponding test standards. American standard ASTM C39 “Standard Test Method for Compressive Strength of Cylindrical Concrete […]
What is Rebound Hammer Test?
Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing. When the plunger of rebound hammer […]
Ultrasonic Concrete Test
Ultrasonic Pulse Velocity (UPV) is an effective non-destructive testing (NDT) method for quality control of concrete materials and detecting damages in structural components. The UPV methods have traditionally been used for the quality control of materials, mostly homogeneous materials such as metals and welded connections. With the recent advancement in transducer technology, the test has […]
