Study of Waste Plastics as Composites Material in Cement Concrete Construction

Abstract

The rapid Urbanization and Industrialization all over the world has resulted in large deposition of Plastic waste. This waste can be utilized under proper condition to reduce the Cement content in Concrete.M20 concrete is used for most of the constructional works, since it gives maximum strength. The strength of this concrete was compared with concrete obtained of shredded Plastic waste varying from 2-8%. Experimental investigations comprised of testing physical requirements of coarse aggregates, fine aggregates, cement and the modifier. M20 concrete was prepared as per IS SP: 23-1982. The said percentage of modifier was blended with the cement concrete mix and the optimum modifier content was found. Cubes were cast and tested for 1, 3, 7, 14 and 28 day strength. These tests revealed that by adding modifier, the strength of concrete increased. At 5% optimum modifier content, the strength of the modified concrete was found to be 1.2 times greater than the plain cement concrete. By using Plastic waste as modifier, we can reduce the quantity of cement and sand by their weight, hence decreasing the overall cost of construction .The Modified cement concrete can be used in the construction of small drainage works and rigid pavement. Which leads to decrease in the overall thickness of the pavement.
