The Improvement of the Strength of Conventional Concrete using Recycled Plastic Bottles

In our modern lifestyle surrounded with plastics &plastics waste. My thesis work is based on the possibility of using plastic bottles in nominal concrete and concrete blocks in civil engineering construction. My works based on the Polyethylene Terephthalate (PET) which is waste product of plastic. PET bottles are used to storing juice, beer, carbonated and non-carbonated drinks. The main parameters were examining like cost per unit, need, volume, color, size, shape etc. PET have the wide range of application in recycling post-consumer, PET is sporadic. In the atmosphere PET explore ecological in balance. To come out for this problem adopting the principle of reuse B and C by Romans. Waste product of PET present physically in to fiber pellet and flakey for partial replacement of aggregates. This research intends to consolidate addressing building construction systems. PET as partial replacement of aggregate in concrete manufacturing which can helps in minimizing the environmental pollution issue. PET as partial replacement of aggregates up to 25% for concrete manufacturing. PET without significant reduction in physically and mechanical properties compared to normal concrete of same grade. Result concluded based on lab test for identification of mechanical properties like compressive strength, split tensile strength and flexural strength done after 7 days, 14 days and 28 days of curing. Concrete mixed design and experiment were done using relevant Indian Standard. The combination of 20% PET shown the optimum performance in terms of mechanical strength.
