This research paper investigates the use of waste marble dust as a soil stabilizer to improve soil properties and enhance its suitability for construction purposes. The study involves the collection and characterization of soil samples from a location in Jaipur district, followed by mixing the soil with varying proportions of marble dust obtained from a marble cutting and polishing industry in Nagaur district. Various laboratory tests, including Atterberg's limits, specific gravity, Proctor compaction, and California Bearing Ratio (CBR) tests, were performed to evaluate the effects of marble dust on soil characteristics. The results reveal that the addition of marble dust to the soil led to a reduction in clay content and an increase in the percentage of coarser particles. The Optimum Moisture Content (OMC) increased, while the Maximum Dry Density (MDD) decreased with higher percentages of marble dust. The plasticity index and swelling properties of the soil were improved, resulting in better volume stability. The CBR values of the soil significantly increased with the incorporation of marble dust, indicating enhanced strength and load-bearing capacity. The findings suggest that marble dust can be a promising soil stabilizer, particularly for engineering projects involving weak soils, offering an alternative to deep or raft foundations and leading to cost and energy savings. The optimal proportion of marble dust for soil stabilization was found to be 15%. Thus, utilizing 15% marble dust content in soil stabilization can yield the best results. The study highlights the potential of waste marble dust as an effective and environmentally friendly solution for soil improvement and construction applications, contributing to resource conservation and reducing environmental pollution.
