An Experimental Analysis of Uses of Polymeric Waste Materials in Concrete

Abstract

Concrete is brittle and weak under  tension, yet robust in compression. As soon as the concrete  is poured, cracks begin to appear. Ordinary concrete is not  allowed to be used in pavements since it causes ductility  and breaking and failure. These flaws in concrete can be  addressed by using fibers as reinforcement in the concrete  mix.[1] Poly-ethylene and tire trash pollute the  environment, resulting in a range of health problems. Poly ethylene and used tires may both be recycled and used as  concrete fibers reinforcement. Poly-ethylene, as we all  know, is a synthetic hydrocarbon polymer with features  such as strength, shrinkage, ductility, and others. The  effects of Poly-ethylene fibers addition on the  characteristics of concrete are investigated in this paper. These fibers Poly-ethylene, and tire fibers; were chopped  into little 30millimeter 6millimeter pieces and employed at  a rate of 1.5 % by volume.[2]  Concrete grades P--30, P--35, and P--40 were utilized. The  concrete mix was designed in accordance with IRC-- 45:2008. The strength characteristics of Poly-ethylene  fibers reinforced concrete FRChave been written down and  provided in the findings of this work. In the laboratory,  shear and flexure strength were determined using a double  shear test and a four-point bending test. There was an  18.10% increase in 28--day compressive strength, a  39.10% increase in flexure, and a 32.0% increase in shear  strength. The trials revealed a 36.10% drop in deflection in  the double shear test and a 22.10% decrease in the 4-point  bending test. Theoretical study of deflections was carried  out using energy techniques. Within the permitted  boundaries, practical values were validated by theoretical  values. Finally, it is possible to infer that tire and Poly ethylene may be employed efficiently in reinforced cement  concrete.
