Experimental investigation on strength properties of concrete using polypropylene pellets

Abstract

The revolution of using new materials as reinforcement in concrete has become all the rage. It is due to the fact that he habitual construction materials we generally use, decreases in quantity on regular basis. Thus there arises a vacuum to replace those habitual materials with the resources of identical property. The good quality river sand has now become a demand because of its scarcity. Thus replacing the conventional river sand with M-Sand (manufactured sand) will reduce this demand. In turn the M sand is readily available at the time of need. M-Sand is of the disposal of plastic waste materials such as polythene bags, water bottle etc., may cause environmental damage. Polypropylene is the second most widely produced synthetic plastic after polyethylene. The usage of polypropylene in concrete will improve its mechanical properties. In this project, M-Sand has been partially replaced by POLYPROPYLENE in the form of plastic pellets in range of (0-30% at the interval of 10%) in M-20 grade of concrete. The concrete has been tested for compressive strength, split-tensile strength and flexural strength for 28 days.
