The literatures on ultrasonic pulse velocity (UPV) as a nondestructive test for evaluating the properties of concrete have been reviewed. Many researchers attempted to correlate compressive strength of concrete to (UPV) and they suggested many equations for this purpose. In this study the reliability of these equations has been investigated. It seems that none of these equations is reliable enough to be recommended to be used in practices. This conclusion may be interpreted on the basis that some properties of composite material, such as compressive strength, are a function of the weakest component, while the UPV through the composite is a function of UPV in all components. Griffith theory is also used to interpret this phenomenon.
