Mechanical Properties Investigation on M40 Grade Cement Concrete by Utilization of Waste Plastic and Crumbled Rubber

Abstract

Waste plastic and crumb rubber is an industrial by product; they possess the problem of disposal as waste and is of environmental concern. In the present era, demand for aggregate in construction industry is increasing rapidly and so, is the demand for cement concrete. Thus, these waste materials become important to seek suitable alternatives for aggregates in future development. My thesis will study the natural coarse aggregate were partially replaced with crumb rubber and waste plastic as aggregate at various proportions like 0, 2.5%, 5%, 7.5%, 10% to find the optimum usage value of crumb rubber in concrete and the natural coarse aggregate is partially replaced with waste plastic at various proportions of 5%, 10%, 15%, 20%, 25% in the obtained optimum value of concrete. Experiment was conducted on M40 grade concrete to determine the compressive strength, split tensile strength and ultrasonic pulse velocity. The results were compared with Traditional concrete.
