Abstract: Concrete is one of the most common materials used in the construction industry. In the past few years, many and modification has been done to produce concrete which has the desired characteristics. There is always a search for concrete with higher strength and durability. Plain concrete has good compressive strength but has low tensile strength, low ductility and low fire resistance. To circumvent these shortcomings, extensive research by concrete technologist has led them to find a very promising concrete material called as fiber reinforced concrete. This study aim to characteristics and comparison of the mechanical properties of PWB, Plastic waste Bags granular concrete with conventional concrete. In order to achieve and verify that 00 %, 10 %, 20 % 30 % fiber percentage by the volume of sand are used in this study with three different concrete mixes test such as Compression test, Split tensile, Bending test and Torsional Test on different specimens for 28days compressive strength, spilt tensile strength, flexural strength, tests have been performed in the hardened state. The total tested specimens are 48. Performance of conventional concrete is enhance by the addition of PWB in concrete. The brittleness in concrete is reduced and adequate ductility of concrete in ensure by addition of PWB in concrete. In this project the behavior of cube, cylinder & beam structures strengthen by using PWB is experimentally tested. The PWB used are fibers in various volume fraction the main reason for adding this to concrete matrix is to improve the post cracking response of the concrete i. e. to improve its energy absorption capacity and apparent ductility and to provide a crack resistance and crack control and addition of strength for bridging the micro-cracks are suggested as the reason for the enhancement in flexural fiber. The torsional test is an attempt made in this study to implement it for further seismic study. In Concrete Natural sand can be replaced with plastic waste by 10 to 30 % to achieve green concrete. Sand can also be replaced up to 30 % in the members of building which do not carry high load. Using plastic waste such as polyvinylchloride (PVC), Polypropylene (PP), Polyethylene in concrete reduces the environmental issues and minimizes the difficulties of dumping the major plastic waste. This will help to tackle the increasing pollution all over the world, especially in countries that face the complications regarding waste. In addition to the environmental benefits, it was noted that using plastic scrap can be used to fight against the obstacle of scarcity of natural sand in India.
