Abstract

Industrial waste may have a severe negative impact on the environment and it releases toxic components that endanger human health and ecosystems, cause major pollution, and upset sensible ecological balances. The use of industrial waste materials in concrete production has gained significant attention due to its potential to address environmental concerns and enhance sustainability. This study focuses on assessing the partial replacement of cement with paint sludge in concrete blocks and its impact on the environment. The experimental investigation involved the incorporation of paint sludge as a cement replacement material in concrete blocks at various proportions, ranging from 0% to 20% by weight. Different qualifying test (compressive strength, slump value etc) were performed to evaluate the performance of concrete. Moreover leaching test of (Cr,Si) was also performed to investigate the environment impacts of paint sludge. The study revealed that 5% replacement had the desirable effect and the results indicated that adding paint sludge had a noticeable effect on the mechanical performance of the concrete blocks. The outcome of the leaching test found that heavy metal and other pollutants were within acceptable limits, demonstrating the potential suitability of paint sludge as a cement replacement material without posing significant environmental risks. Overall, this study provides valuable insights into the feasibility of utilizing paint sludge as a partial replacement for cement in concrete block production. The findings suggest that such an approach can contribute to environmental sustainability by reducing waste generation and lowering the environmental impact associated with conventional concrete production.
