Soil stabilization by integrating dust particles with calcium lignosulphanate

Abstract

This paper analyzes the stabilizing effect of stone dust, granite dust, marble dust, and calcium lignosulphonate on construction materials and natural soils during road construction. The ultimate aim was to enhance the soil’s engineering properties such that the pavement constructed could correctly withstand the load applied. To achieve this, every stabilizer was amalgamated with the soil at various percentages between 5 and 50%. Measurements were made of Atterberg limit tests, moisture content, and specific gravity. The research demonstrated that a diminution in optimal moisture content was seen, with an elevation in maximum dry density and California bearing ratio (CBR). Enhancements in the unconfined compressive strength were also identified. The outcomes determined that the untreated soil’s CBR was 2.27% and in the case of soil with 45% additives, the CBR attained was 5.05%. When the soil was mixed with 50% additives, performance of 30.21%, 17.42%, and 12.82% was exhibited for (a) liquid limit, (b) plastic limit, and (c) plasticity index. Moreover, via the addition of presented stabilizers, the soil’s mechanical properties were elevated appreciably.

From Bibliometric Analysis to Experimental Validation: Bibliometric and Literature Review of Four Cementing Agents in Soil Stabilization with Experimental Focus on Xanthan Gum

“…This includes detailed cost analyses and case studies in real projects. Moreover, the interaction between these stabilizers and other construction materials, such as chemical additives, geotextiles, and other soil stabilizers, must be studied to ensure compatibility and optimize stabilized soil performance [6,82]. Finally, the long-term effects of these materials on the environment and human health need to be evaluated to ensure they do not pose risks.…”
