Utilisation of Industrial Waste for Manufacturing High-Performance Sustainable Brick

The growing demand for sustainable construction materials has driven the development of eco-friendly alternatives to traditional fired bricks. This study focuses on the use of industrial by-products and alternative materials such as fly ash, ground granulated blast furnace slag (GGBS), hydrated lime, crushed sand, and Ordinary Portland Cement (OPC) to manufacture unfired composite bricks. Three different proportions of these materials were used to prepare brick samples, designated as M1, M2, and M3. For each mix, three samples were prepared for testing. The bricks were cured and tested over periods of 7, 14, and 28 days to evaluate their compressive strength and other physical properties. The results showed that mix M1 achieved the highest compressive strength of 13.04 MPa at 28 days, meeting the standards required for structural applications. The successful incorporation of waste materials not only reduces environmental impact but also provides a cost-effective and energy-efficient solution for the construction industry. This project demonstrates the viability of unfired bricks as a sustainable building material, promoting green construction practices while maintaining structural performance.
