In overall world the major issues now days are dumping of waste materials. The dumping of waste material in environment causes harmful disease and pollutes the surrounding areas. This research aims to employ industrial waste materials like waste foundry sand (8 %, 16 %, and 24 %) and lime (3 %, 6 %, and 9 %) in the stabilisation of clayey soil so the combined mixture is being utilized as a sub-grade. On waste foundry sand and lime, various tests such as compaction, particle size distribution, Atterberg's limits, specific gravity and California bearing ratio were performed. According to the research, the addition of 16 percent waste foundry sand and 6 percent lime produces the highest dry den... More >
