Experimental Performance Evaluation of Plastic Waste-Based Bricks

Abstract

The increasing accumulation of plastic waste and the environmental impact of conventional construction materials have encouraged the exploration of sustainable alternatives in the building sector. Plastic waste–based bricks have emerged as a promising solution that integrates waste management with eco-friendly construction practices. This study presents an experimental performance evaluation of bricks manufactured using plastic waste combined with conventional materials. The experimental program focused on assessing key performance parameters, including compressive strength, water absorption, density, and durability, to determine their suitability for construction applications. Bricks were prepared using controlled mix proportions and subjected to standard curing periods, followed by laboratory testing in accordance with relevant testing procedures. The results indicate that plastic waste–based bricks exhibit satisfactory mechanical performance, low water absorption, and good resistance to moisture ingress compared to conventional clay bricks. The hydrophobic nature of plastic significantly reduces porosity, enhancing durability and service life, particularly in humid environments. In addition to technical performance, the use of plastic waste contributes to reduced landfill disposal and conservation of natural resources. The findings demonstrate that plastic waste–based bricks are viable for non-load-bearing and low-stress construction applications. This experimental evaluation supports the potential of plastic waste bricks as sustainable, cost-effective alternatives, while highlighting the need for further research on long-term performance and standardization.
