Lightweight Concrete is a concrete using different type of lightweight aggregate that replace the material from normal concrete mixture. The utilization of lightweight aggregate in concrete is mainly to reduce the self-weight of concrete, which leads to reducing the dimension of foundation and that results in cost saving. The material that has been selected is recycled plastic as replace material in concrete mixture. Most research state that the addition of plastic can affects the workability, thermal conductivity, density and mechanical properties such as compressive strength, modulus of elasticity, split tensile strength and slightly enhances the abrasion and flexural strength. From previous study, reported the 28-day concrete compressive strength from ranging 34 to 70% is significantly reduced when 20 to 100% of the conventional fly ash was substituted directly with plastic. Similarly, replacing 30 to 80% of the conventional course aggregate directly with plastic resulted in a substantial reduction (ranging from 65 to 78%) in the 28-day concrete compressive strength. This paper is to presents an overviews different type of research that has be conducted for the potential of mechanical properties of the lightweight concrete containing plastic waste. The effect of recycled plastic for the mechanical properties also presented in this paper.
