Influence of replacing aggregates by recycled waste plastic on the mechanical properties of concrete: A review
AI summary Read the abstract
This review examines how incorporating recycled plastic aggregates into high-strength concrete affects its physical and mechanical properties, finding that while compressive strength decreases, concrete with recycled plastic remains viable for many engineering applications and offers benefits such as enhanced energy absorption and sulfuric acid resistance.
The rapid escalation in plastic production and consumption has resulted in a substantial increase in plastic waste, presenting serious environmental issues. In recent years, researchers have explored the possibility of using recycled plastic as an alternative aggregate in high-strength concrete, aiming to mitigate plastic waste and improve sustainability in construction practices. This study reviews the effects of incorporating recycled Plastic Aggregates (PA) on the properties of high-strength concrete. The review examines the effect of PA on concrete's physical, mechanical, and durability characteristics, highlighting both the potential benefits, such as enhanced energy absorption and sulfuric acid resistance, as well as limitations, including reduction in compressive strength. Current research indicates that despite changes in mechanical properties, concrete with recycled PA remains viable for many engineering applications. The findings confirm the need for further investigation into pre-treatment methods to optimize plastic aggregate performance, contributing to sustainable waste management and eco-friendly construction solutions.
