Relationship between compressive strength and UPV for high strength concrete containing expanded Perlite aggregate

Ultrasonic non-destructive testing methods are frequently used to estimate the quality of concrete. These methods are typically based on the measurement of the propagation of velocity, which is closely related to mechanical properties and, more directly, to the modulus of elasticity. Non-destructive testing methods consider concrete as a homogeneous material (Krautkramer & Krautkramer, 1990).
