An overview of methods and materials for sandy soil stabilization: emerging advances and current applications

Aims: Nowadays, the depletion of renewable resources and production particulate matter brought on by desertification and the subsequent dust storms pose a serious and immediate threat to human health. The purpose of this study is to investigate the stabilization methods applicable for desert dust as well as sandy soils to prevent desertification and dust-related negative consequences. Materials & Methods: The methodology used in this research is a complete review of the provided sources and evaluation of their results in the last two decades in this field. This review deeply investigates the methods and Materials of stabilization of desert sandy soil. Findings: Chemical stabilizers of loose sand, including cement, lime, nanoclay, blast furnace slag, polymer, fly ash, and other stabilizers, have been used in different countries of the world and have shown acceptable results. The results of the studies show that by using these methods and stabilizing materials, wind erosion can be reduced by ۷۰% and the compressive strength of the soil can be increased by up to ۲ times its initial value. Conclusion: We draw the conclusion that we will require a green and reasonably priced stabilizer to stabilize the desert dust based on the study we have done and the analysis of the papers that have been presented in this sector. Given the limitations and drawbacks of the aforementioned stabilizers, a good stabilizer doesn't destroy the soil's vegetation, doesn't significantly alter the soil's color, texture, or chemical composition, and doesn't interfere with the roots' ability to breathe.
