Abstract

Structures are assemblies of load carrying members capable of safely shifting the superimposed loads to the foundations. Their main and most looked after things is the strength of the material that they are made of. Concrete, as we all know, is an integral material used for construction dedications. Thus, strength of concrete used, is essential to be ‘known’ before starting with any kind of analysis. In the recent past, various methods and techniques, called as Non-Destructive Evaluation (NDE) techniques, are being used for Structural Health Monitoring (SHM). The perception of nondestructive testing (NDT) is to obtain material properties of in place specimens without the damage of the specimen nor the structure from which it is taken. However, one problem that has been dominant within the concrete industry for years is that the true properties of an in-place specimen have never been tested without leaving a certain degree of damage on the structure. For most cast-in-place concrete structures, construction provisions require that test cylinders be cast for 28-day strength determination. Usually, demonstrative test specimens are cast from the same concrete mix as the larger structural elements. The rebound hammer test is classified as a hardness test and is based on the principle that the rebound of an elastic mass be determined by on the hardness of the surface against which the mass impinges. The energy absorbed by the concrete is correlated to its strength. There is no exceptional relation between hardness and strength of concrete but experimental data relationships can be obtained from a given concrete. However, the term “nondestructive” is given to any test that does not harm or affect the structural behavior of the elements and also leaves the structure in an satisfactory condition for the client. The use of the ultrasonic pulse velocity tester is introduced as a tool to monitor basic initial cracking of concrete structures and hence to present a threshold limit for possible failure of the structures.
