The use of hybrid fiber reinforced concrete has attracted because cementitious material including different type of fibers in suitable combination performs better compared to mono fiber reinforced concrete. In this study I have investigated the performance of concrete containing Polyethylene Terephthalate (PET) bottle waste fibers along with polypropylene fibers as a hybrid fiber reinforced concrete. The PET fibers are obtained by simply cutting the bottles. PET bottle waste was chosen because it is being thrown after single use and cause environmental problem. In present investigation fresh properties as well as mechanical properties of individual fibers and hybrid fibers for various proportions of fibers are found out. The workability of fresh concrete is determined by slump cone
and compaction factor test also results of compressive strength, split tensile strength and flexural strength were studied. The use of waste PET bottle fibers with polypropylene fibers in concrete has been shown interesting improvements in concrete performance.
