The responsible management of construction and demolition waste is a critical issue, primarily due to the substantial volume of waste generated. Landfilling remains a prevalent method for disposal. This project explores the use of construction and demolition waste (C&D) as a substitute for coarse aggregate in cement brick production, with varying percentages (ranging from 0% to 100%). Various mix types were employed in the casting of these bricks. The study encompasses the evaluation of compressive strength at intervals of 7, 14, 21, and 28 days, as well as the implementation of water absorption tests, alternate drying and wetting tests, and examinations for sulphate and chloride attacks.
