Durability and Environmental Performance Evaluation of Eco-Friendly Construction Materials under Accelerated Weathering Tests

Abstract

The construction sector is a major contributor to global resource consumption and environmental degradation, necessitating the development and adoption of eco-friendly construction materials with reduced environmental impact and long-term durability. While sustainable materials such as geopolymer concrete, recycled aggregate composites, bio-based binders, and natural fiber-reinforced materials have demonstrated promising environmental benefits, their long-term performance under harsh environmental conditions remains insufficiently understood. This study presents a comprehensive durability and environmental performance evaluation of selected eco-friendly construction materials subjected to accelerated weathering tests. Materials were exposed to controlled cycles of ultraviolet radiation, moisture ingress, thermal fluctuations, and chemical attack to simulate long-term aging. Mechanical strength retention, microstructural stability, water absorption, and surface degradation were systematically assessed. Results indicate that eco- friendly materials exhibit varying resistance to environmental stressors, with geopolymer-based systems demonstrating superior durability and lower degradation rates compared to bio-composites. The findings provide critical insights into material selection, lifecycle performance, and sustainable construction practices, supporting the wider adoption of environmentally responsible materials in infrastructure development.
