The construction industry is a major consumer of natural resources and a significant contributor to environmental degradation. Recycled Aggregate Concrete (RAC) offers a sustainable solution by utilizing construction and demolition (CD) waste to produce concrete bricks. This research investigates the feasibility of manufacturing concrete bricks using recycled aggregates, replacing natural aggregates partially or fully. Experimental analysis involved preparing bricks with varying recycled aggregate content (0%, 25%,50%, 75%, and 100%) and testing their mechanical properties and durability. Results indicate that bricks with up to 50% recycled aggregates exhibit compressive strength and durability comparable to conventional bricks, making them suitable for non-loadbearing applications. This study highlights RAC bricks as a cost-effective, eco-friendly alternative, contributing to resource conservation and waste reduction.
