Sand erosion is one of the major challenges to soil and soil-structure systems. This paper investigates the potential use of clay additives to reduce fine sand erodibility, with particular focus on Nano Kaolin additive. In this paper, the Pocket Erodometer Test (PET) technique was used to assess the fine sand erodibility before and after treatment with the additives. The optimum mass percentage of Nano Kaolin additive was found to be 2%, which decreases the fine sand erodibility by about 90%. When the treated sample was immersed in water for 24 h, simulating a possible flood condition, the improvement was reduced to 70%, which is still significant. In addition, a sonicator was used to uniformly disperse the Nano Kaolin particle before its application to the untreated fine sand. The sonicated Nano Kaolin had a better performance with about 95% improvement in erodibility. As a first step towards large scale application, spraying of the Nano Kaolin-water solution on the erodible sand was tested and was found to have about 80% efficiency (as compared to 95% efficiency of mechanical mixing) which is still a significant improvement. Scanning electron microscope (SEM) imaging reveals uniform adhesion of Nano Kaolin to sand particles, explaining the induced cohesion and decreased erodibility of the treated fine sand.
