Abstract:

Bricks remain one of the most fundamental materials in the construction industry, primarily used for building houses and infrastructure. However, the increasing demand for construction materials has put pressure on natural resources, requiring engineers to explore sustainable and durable alternatives beyond conventional brick production. This study investigates the feasibility of using ceramic tile waste as a partial replacement for coarse aggregate and quarry dust as a fine aggregate substitute in the production of concrete bricks. By incorporating these waste materials, the research aims to develop an eco-friendly and cost-effective alternative while maintaining structural integrity. For this experimental study, M10-grade concrete was used to manufacture concrete bricks. The mix design involved replacing natural coarse aggregate with ceramic tile waste at varying proportions of 10%, 20%, 30%, 40%, and 50%, while quarry dust was kept constant at 50% replacement of fine aggregate. Brick specimens of 100mm x 100mm x 100mm were cast and subjected to various tests to assess their mechanical and physical properties. These tests included shape and size verification, compressive strength analysis, water absorption test, fire resistance test, soundness test, drop test, efflorescence test, color assessment, and structural integrity evaluation. The experimental results indicate that incorporating tile waste and quarry dust in concrete bricks significantly enhances their strength and durability. The compressive strength of the bricks showed an increasing trend up to an optimal percentage of tile waste replacement before experiencing a slight decline at higher replacement levels. Water absorption rates remained within permissible limits, suggesting good density and compactness. Additionally, fire resistance and soundness tests demonstrated improved thermal and acoustic insulation properties, making these bricks suitable for various construction applications. The efflorescence and drop tests confirmed the durability and weathering resistance of the alternative bricks, further supporting their potential for practical use. Utilizing ceramic tile waste and quarry dust in concrete brick production not only reduces reliance on natural aggregates but also addresses the growing issue of construction waste disposal. This approach promotes sustainable construction practices by minimizing environmental impact and providing a cost-effective solution for affordable housing. Future research can focus on optimizing mix proportions, assessing long-term durability, and exploring large-scale implementation. The study concludes that concrete bricks incorporating tile waste and quarry dust offer a promising alternative to conventional bricks, ensuring a balance between environmental sustainability, economic feasibility, and structural performance.
