Can Ultrasonic pulse velocity test be used to determine parameters for non cement concrete material such as limestone ( used to build in heritage structures) ? if it is possible, how to measure parameters ? What are the guidelines?
Ultrasonic Pulse Velocity (UPV) test is a non-destructive and reliable testing method used to evaluate the integrity of concrete and other materials. This test can determine concrete's physical and mechanical parameters, such as compressive strength, flexural strength, and modulus of elasticity. The UPV test is also used to detect the presence of any cracks, voids, and other defects in concrete. In recent years, there has been an increasing interest in using the UPV test to evaluate non-cement concrete materials. Non-cement concrete materials do not contain Portland cement as a binder. These materials include recycled aggregate concrete, fiber-reinforced concrete, fly ash concrete, geopolymers, and others. The UPV test can be used to evaluate the physical and mechanical parameters of non-cement concrete materials as it does for ordinary concrete. The UPV test can determine these materials' compressive strength, flexural strength, and modulus of elasticity. The UPV test is also used to detect the presence of any cracks, voids, and other defects in non-cement concrete materials. The UPV test is a reliable and inexpensive method for evaluating non-cement concrete materials. The test is relatively easy to perform, and the results can be quickly obtained. The UPV test is also a non-destructive method and does not require sample preparation or destruction of the material being tested. The test is also suitable for materials that are not easily accessible or too large to be tested using other methods.

Yes, you can use Ultrasonic Pulse Velocity test to determine the parameters of non-cement concrete materials such as rock or limestone. You can measure the parameters using ASTM standard: Standard Test Method for Laboratory Determination of Pulse Velocities and Ultrasonic Elastic Constants of Rock D 2845 – 00. This test method describes equipment and procedures for laboratory measurements of the pulse velocities of compression waves and shear waves in rock and the determination of ultrasonic elastic constants of an isotropic rock or one exhibiting slight anisotropy.
Yes, you can use UPV test to determine physical and mechanical parameters such us the modulus of elasiticity of non-cement concrete materials. It is a non destructive testing (NDT) which aims to inspect a part or structure while respecting its integrity. The Pundit Lab test instrument can be useful to examine all types of concrete compounds, with a bandwith of 20-500 kHz, a correlation of compressive of concrete and rocks is possible with this tool.
