Experimental Investigations on Partial Replacement of Coarse Aggregate by Waste Plastic and Waste Marbles in Concrete

Abstract

Plastic waste is big issue in todays environments and which results in public health issues. Now a days public does not have any alternative on any kind of plastic produce so, to overcome this problems, plastic products are used in construction industries due to scarcity of cement, sand, aggregate in future. This review paper includes the partial replacement of waste plastic(20%)as a coarse aggregate and studied the properties of waste plastic in concrete. large amount of waste has been produced during mining and processing stages by Marble industry. This waste is dumped on to open land which creates a lot of environmental problems. The main objective of this study was utilization of marble waste as a replacement for conventional natural coarse aggregate in concrete. Experimental investigations were carried out to determine the accessibility of use of marble waste as a coarse aggregate in concrete. Conventional natural coarse aggregate was replaced by marble aggregate in different percentages 40% by weight. The average compressive strength of all the concrete mixes containing marble aggregate increased 40% by weight. From the results it was found that, the workability, compressive strength and permeability increased with increase in substitution of marble aggregate. This paper represents a collection of ideas of various studies done on the use of Waste Plastic and waste marbles Materials in concrete mixes. Conclusions are drawn based upon the respective results of all the mentioned research papers.
