Utilization of Industrial Waste

The search for eco-friendly solutions has become imperative with the increasing environmental issues related to the disposal of foundry waste and sand mining. The potential of industrial waste materials such as fly ash, blast furnace slag, and red mud as partial replacements for silica sand in foundry molds is investigated in this research. Mechanical properties such as mold hardness, permeability, and green compressive strength were evaluated experimentally. The results indicate that the substitution of sand with certain industrial waste materials at 20–30% results in the enhancement of collapsibility and decrease in resource usage without compromising quality castings. Industrial by-product utilization is beneficial in two ways, according to the study: it reduces environmental pollution and minimizes dependence on natural sand resources, promoting green foundry technology.
