Utilization of waste glass and demolished brick as coarse aggregate for sustainable concrete production

Cement is a vital global construction material, primarily used in concrete production, consisting of inert mineral aggregates like sand, gravel, crushed stones, and cement. crushed brick aggregates in concrete face challenges due to regulations on impurities, water absorption, and lack of understanding of concrete behaviour. The research aimed to prepare sustainable concrete by using waste glass and demolished brick, study the physical and mechanical properties of the concrete produced, and examine the effect of adding broken brick and waste glass as coarse aggregates. The study involved the creation of five different concrete compositions using varying percentages of waste glass and demolished brick, which were then subjected to a curing process for 1, 14, and 28 days. The samples were tested for compressive strength, water absorption and Optical Microscopy. On the 14th day, sample B demonstrated optimum results with a compressive strength of 15.34 MPa and a water absorption rate of 8.4%.
