Some Factors Affecting the Ultrasonic Pulse Velocity Test Results of High Strength Concret

Abstract

The high strength concrete is characterized by its high strength, low porosity and good performance under aggressive environmental conditions. The paper presents some factors affecting the Ultrasonic Pulse Velocity test results for high strength concrete such as water/ cement ratio, type of aggregate, frequency level of transducers, dimension of the specimens and path length. An experimental equation has been derived for the prediction of compressive strength of high strength concrete from pulse velocity, which can be used for the estimation of strength.It provides more reliable prediction and can be used in precast concrete factories manufacturing precast concrete girders for bridges.
