Recently, waste utilization in soil improvement has become immensely popular regarding the optimization of waste disposal, economy, and environmental protection. Most industrial wastes are environmentally hazardous. In this study, xanthan gum, which is an eco-friendly biopolymer, was utilized in soil improvement. Model experiments were carried out to investigate influences of water content, optimum xanthan gum ratio, blending technique, enhancement thickness and curing duration. Consequently, approximately 4.47 times bearing capacity improvement and 3.5 times settlement reductions were attained. Besides, optimum values of 1.75% for the biopolymer ratio, 80°C for the mixing temperature, 42 days for the curing period and 0.75% for the improvement depth were determined. The findings of microstructural analyses also stood up for the existence of chemical and physical improvements in the soil structure.
