Experimental Studies on Flexural Behavior of Waste Plastic Fiber Reinforced Concrete Slab

Plastic disposal is challenging issue across the globe. The use of plastic in concrete will overcome the disposal problem. In this paper, we study the possibility of disposing waste in concrete. The effect of fiber is been studied for varying percentages of fiber 0.5% to 3.0% by weight of cement, with a variation of 0.5 % interval. The effect of fiber is been studied for two types of dispersion of fiber 1.Dispersed both in tension and compression zone 2.Dispersed only in tension zone. The flexural strength of slab with fiber reinforced concrete for nine point loading is been studied, the grade of concrete considered is M20. The results are compared with conventional concrete. It is been found that with the addition of fiber the strength of concrete considerably increases. Addition of plastic fiber of 1.5% shows the maximum increase in strength of concrete. The addition of plastic fiber increases the strength maximum at first crack level compared to ultimate load level. The number of cracks developed in fiber reinforced concrete is very less compared to conventional concrete.
