Review Paper : Testing of Ultrasonic Pulse Velocity on Concrete

Concrete is most basic material used for any kind of engineering construction. The performance of concrete is been influenced by various factors like water-cement ratio, size of aggregates and its type, the weather conditions, cement type and admixtures. This further results in affecting the compressive strength and the durability of the concrete structure. There are two types of method for determining the strength of concrete; they are destructive and non-destructive method. One of the effective, easiest and less time consuming method of non-destructive in-situ test is Ultrasonic Pulse Velocity. This test determines quality, uniformity, cracks, defects, homogeneity, honey comb voids present in concrete specimens and evaluating dynamic modulus of elasticity. The pulse velocity depends upon the compaction of material, length of the specimen, path length, presence of reinforcement steel, moisture content of concrete, temperature of concrete.
