Abstract: While the use of plastics has gradually increased in our daily lives due to its user-friendly features, lightness and cost-effectiveness, scientific and engineering communities have raised their concerns in recent decades regarding the harmful effects caused from the usage and disposal of plastics on our environment. Also, from an environmental point of view, concrete production heavily contributes to greenhouse gas emissions and the majority of construction materials are produced from natural resources. Therefore, there exists a need for developing sustainable concrete that leaves less carbon footprint and requires fewer natural resources. In this regard, utilizing waste/recycled plastics in concrete can be a viable alternative that offers obvious ecological and environmental benefits. Numerous researchers and engineers have investigated the feasibility of using various types of plastics in concrete production. Since different types of plastics possess engineering properties that are different from conventional constituents of concrete, it is important to understand how adding plastics would alter the characteristics and behavior of concrete. This paper presents a methodical review on recent researches that used waste/recycled plastics as an additive or a partial replacement of aggregates in concrete, and discussed their effects on various properties of concrete.
