Utilization of Plastic Waste (PET Bottles) and Fly Ash in Concrete: A Review

Abstract

Origins of all basic ingredients of concrete are nature and reducing with an increase in the consumption of concrete. It requires finding alternate material that can be utilized in the production of concrete; the revolutionary in the construction industry called green concrete, which is produced by adopting the wastes. In this study, a review is done on previously reported work for the utilization of fly ash and plastic waste in concrete. Many research works have been studied and it is concluded that the major focus was to evaluate the effect of fly ash and plastic waste on the fresh concrete property such as workability and hardened concrete properties such as compressive strength, flexural strength, split tensile strength; whereas much of durability properties are yet to be studied. Also, the behaviour of the green concrete post-fire exposure has not been dealt so far.
