A Novel Concrete By Using Waste Plastic Aggregate As Partial Replacement Of Natural Coarse Aggregate
Abstract
Plastic waste is silent problem to the environment and their disposal is a very dangers issue for waste management.in past various attempts was made through experimentation to check the feasibility of plastic waste to be use partially in concrete. In this research work test were conducted to find out the properties of plastic aggregate such as crushing value, impact value, flakiness and elongation index, specific gravity, bulk density and voids. These properties of plastic aggregate were compared with the properties of natural aggregate. The compressive strength test, split tensile strength test and flexural strength test were performed. Effect of replacement of natural coarse aggregate with various percentages (0% to20%) of plastic aggregate was studied. Behavior of concrete of M20 grade was experimentally investigated and the optimum percentage replacement of natural coarse aggregate was found out. It is found that the use of plastic aggregate results in the formation of light weight concrete. The compressive, tensile and flexural strength of concrete reduces with the increase of percentage of replacement of plastic aggregate.
