Abstract
Recently times, industrial development has increased, including plastic industries, and since plastic has a very long analytical life, it will cause environmental pollution. Therefore studies have resorted to reusing recycled plastic waste (sustainable plastic) to produce environmentally friendly concrete (green concrete). In this research, some studies were reviewed and then summarized into several things, including the percentage of plastic replacement from the aggregate and the effect of this percentage on the fresh properties of concrete, such as the workability and the effect of plastic waste on the hardening properties of concrete such as dry density, compressive, tensile and flexural strength.
Highlights
Plastic waste disposal is one of the environmental problems that increase with the increase in industrial development
The reason for the decrease in the compressive strength when increasing the proportions of plastic replacement is due to the weak bonding strength between the cement paste and the plastic (HDPE)
Using plastic waste in the concrete lead to reduce of landfill cost and reducing the environmental pollution
Summary
Plastic waste disposal is one of the environmental problems that increase with the increase in industrial development. Production of lightweight structural concrete with a maximum of 1850 kg/m3 by using polyethylene Terephthalate waste (PET) as a coarse aggregate where the produced plastic is heated, cooled, and crushed to different gradients (Zebua,2017). Plastic waste is often buried, and this process causes potential environmental risks. The partial solution to environmental problems is the exploitation of plastic waste. The use of plastic waste in building materials and concrete reduces environmental pollution and helps to reduce concrete costs. The process of recycling waste plastic is expensive, and plastic does not decompose but it takes a long time to decompose, which leads to major environmental pollution problems.
