Properties of concrete can be modified using fibre in concrete. Using fibre from waste of plastic in concrete to some chance increases strength as well as durability of concrete and break disposal problems of plastic waste in terrain. From electronic waste Polyvinyl chloride lines (PVC) are used as fibre and from polypropylene (PP) quilting bag of cement are used as fibre in concrete. Both are used in 0, 0.26, 0.51, 0.76 and 1% by weight of cement in concrete. Total 90 samples conforming of 9 cells with 0% fibre, 36 cells with PP fibre of 0.26%, 0.51%, 1, 36% cells of PVC fibre of 0.26%, 0.51%, 0.76%, 1% and 9 cubes of mongrel and average values are calculated.  Both Fresh and harden properties of polypropylene fibre reinforced concrete and polyvinyl chloride fibre reinforced concrete is determined and mongrel of optimum values calculated is used in a single blend and compressive strength is calculated. Results show that 0.76% and 0.51% is optimum value of polyvinyl chloride fibre RCC and polypropylene fibre RCC with 49% and 17.5% increase in concrete strength compared to normal concrete independently and can be used in a single admixture. The mongrel fibre RCC of optimum values of PPFRC AND EFRC show 56% increase in compressive strength. In hybrid fibre concrete with reinforcement, polypropylene fibre keeps cracks small and polyvinyl chloride fibre shows improvement in mechanical properties.
