An Investigation of Physico-Mechanical Properties of Some Chosen Concrete Mixtures by Ultrasonic Pulse Velocity (UPV) Techniques

P.Kuppuraj | S.Gunasekaran

Abstract: On a human time-scale, small usages of concrete go back for thousands of years. Structures made of concrete can have a long service life. Concrete is the most widely manufactured and durable construction material. Use of concrete produces a wide range of environmental and social consequences. Some are harmful, some welcome, and some both, depending on circumstances but the evaluation of concrete properties is of great interest, whether to detect altered areas or to control the concrete quality and estimate its compressive strength i. e. Physico-Mechanical Properties. The standard methods used to assess the quality of concrete in concrete structures on specimens cannot be considered. The disadvantage of destructive technique is that results are not immediately known, the number of specimens or samples is insufficient for an economic reason, still does not reflect the reality of the structure [1]. One of the principal objectives of the development of Non Destructive Testing (NDT) techniques is a reliable assessment of defects of concrete members even when they are accessible only from a single surface. The Ultrasonic pulse velocity (UPV) and Rebound Hammer (RH) tests are often used for assessing the quality of concrete and estimation of its compressive strength. Several parameters influence this property of concrete as the type and size of aggregates, cement content, the implementation of concrete, etc. The main advantage of Ultrasonic Pulse velocity method is to avoid the concrete damage on the performance of building structural components. Additionally, their usage is simple and quick and the test results are available on site and also the cores cannot be drilled. So that, In this present study, we would like to investigate the Physico-Mechanical Properties of the chosen five numbers of Concrete Specimens namely, C1, C2, C3, C4 and C5 i. e. Aggregates replaced by broken bricks, Waste ceramic tiles, Aggregates Partially replaced by waste tyres, Aggregates with Quarry dust and Addition of Sisal fibres and Addition of Poly Ethylene Glycol (PEG) 400 respectively by using the NDT Techniques of Ultrasonic Pulse Velocity (UPV) and Rebound Hammering (RH). We also interested to correlates the Macro level futures of these chosen Concretes to their micro properties and conclude which is the best replacer of partial aggregates to made Eco-friendly and quality as well as economically suitable concrete mixtures for general purpose building constructions.
