Long-Term Compressibility and Shear Strength Properties of Cement-Treated Clay in Deep Cement Mixing Method

This study investigated the physical and mechanical properties of Malaysian kaolin clay treated with cement using unconfined compression strength and Oedometer tests. The objective was to simulate the actual conditions of soil–cement column installation employing the deep soil mixing method with cement slurry over a 180-day period. Cement content varied between 5%, 10%, 15%, and 20%. To ensure homogeneous mixing and workability, water content was maintained between the liquid limit and twice the liquid limit. Results indicated that increasing cement content enhanced the unconfined shear strength and elasticity modulus of the stabilized soil while decreasing water content after curing. Consolidation tests revealed a diminishing slope of the void ratio curve with increasing cement content and curing time. This study further introduced precise correlations between the void ratio and compression characteristics of cement-stabilized clay, achieving high accuracy. Additionally, the research conclusively demonstrated a robust linear correlation (R2 = 0.99) between unconfined compressive strength and consolidation yield pressure.
