Experimental Investigation on Steel Fibre Reinforced Concrete Made Pet Waste Pet Waste with Partial Replacement of Coarse Aggregate

Abstract

-Concrete is a composite material consisting of mortar and coarse aggregate.An existing problem of concrete is formation of crack.In this study feel fibres are added in concrete to control the concrete 1,1.5,2%of steel fibre is added in concrete, which is the efficient percentage of addition in reinforced concrete. In addition to that to overcome the scarcity of conventional coarse aggregate now-a-days usage of (PET)poly ethylene terephthylate is highly recommended. A conventional method is proposed by using (PET)poly ethylene terephthlate as partial replacement of coarse aggregate to its weight with addition of 1,1.5,2% of steel fibre to the volume of concrete in specimen. Cube of size 150 x 150 x 150 mm is casted and tested, which is designed according to Indian standard codes. The flexural properties of the cube are compared between control specimen and 5%, 10%,15% and 20% partially replaced (PET )poly ethylene terephthalate as coarse aggregate specimens INTRODUCTION:Concrete is known as a brittle material with low bearing capacity for deformation under tensile stress. The development of these tensile stresses are mechanical loading, harmful reactions and environmental loading. Cracks which affect the structural performance of the concrete are caused mainly due to this stress. In order to control the formation of and development of these cracking fibre are introduced in concrete.
