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 >

This study focuses on the green synthesis of iron oxide (Fe2O3) nanoparticles using guava leaf extract as a reducing agent. The methodology involves the extraction of guava leaves to create an aqueous reagent solution, followed by the synthesis of Fe2O3 nanoparticles through a series of processes including centrifugation and annealing. The synthesis procedure involved mixing the guava extract with an iron nitrate solution, stirring, and allowing the formation of nanoparticles, which were subsequently annealed at 600°C. Characterization of the resulting nanoparticles was carried out using X-ray diffraction (XRD), revealing a rhombohedral structure with an average crystallite size of approxim... More >
