Abstract: Against the backdrop of global climate change, the intensification of the greenhouse effect and the growing challenge of resource scarcity have become increasingly prominent, presenting significant limitations to conventional soil improvement techniques that predominantly rely on chemical additives such as cement. This study explores the modification of laterite using glyceryl monostearate (GMS) to enhance its mechanical performance and water resistance. Experimental results demonstrate that both the compressive and tensile strengths of laterite initially increase and subsequently decrease with increasing GMS content, with 2% identified as the optimal incorporation level. At this concentration, GMS forms a hydrophobic protective layer on the surface of soil particles, thereby significantly improving mechanical strength. The integration of GMS markedly enhances the hydrophobic characteristics of laterite, extending the water droplet penetration time from approximately 5 s in the original sample to a maximum of 916 s. This effectively prevents direct interaction between water molecules and soil particles. Furthermore, GMS effectively reduces the rate of water evaporation and mitigates the formation of dry shrinkage cracks, with enhanced efficacy observed at higher dosages. Mercury intrusion porosimetry (MIP) analysis reveals that GMS modifies the pore structure of laterite by increasing the total pore volume and the proportion of micropores, thereby improving the structural stability of the soil. This study contributes innovative insights and methodologies for the sustainable improvement of laterite and provides scientific evidence and technical support for its effective application in high-humidity environments and hydraulic engineering projects.
