Abstract- – This study investigates the mechanical performance and sustainability of modified clay bricks incorporating waste glass powder (WGP) and various agro-industrial byproducts, targeting their application in green building construction. Motivated by the growing demand for sustainable construction materials, the research evaluates the compressive and flexural strength, water absorption, and durability of bricks infused with different waste materials such as cocoa shells, sugarcane bagasse, and rice husk ash. The optimal WGP content of 20% resulted in a 25% increase in compressive strength and a 41% improvement in modulus of rupture, while maintaining water absorption levels comparable to traditional bricks. Microstructural analyses using SEM and XRD reveal enhanced bonding and reduced porosity in modified bricks. The study also explores the environmental and economic benefits of utilizing recycled crushed clay bricks (RCB) in pavement construction and evaluates their performance in cement-stabilized macadam (CSM). The integration of waste materials not only reduces reliance on virgin clay but also offers substantial reductions in energy consumption and CO₂ emissions. The findings affirm that modified bricks with waste additives provide a viable solution for sustainable infrastructure, aligning with global green building initiatives.
