“…The efficacy of CKD in the process of soil stabilization is heightened when employed in combination with additional substances, such as polypropylene fibers, which enhance the material's ability to undergo deformation without experiencing fractures and subsequently reinforce it. Furthermore, the inclusion of glass fiber in fine-grained soil results in the improvement in its physical and mechanical characteristics, thereby increasing its stability and ability to bear loads [19,31]. The use of Cement By-Pass Dust (CBPD) in soil stabilization has shown improvements in the properties of expansive clay, showing similar results to those achieved with lime or cement [28].…”

“…When combined with glass or polypropylene fibers, CKD impacts the physicochemical properties, geomechanical strength, and ductility of fine-grained soil. This addresses the brittle nature of CKD-stabilized soils and underscores the importance of considering mechanical and thermal properties in construction applications [19,31].…”

Soils in Saudi Arabia are emerging as potential sustainable building materials, a notion central to this study. The research is crucial for advancing construction practices in arid areas by enhancing soil thermal properties through stabilization. Focusing on Hejaz region soils, the study evaluates the impact of stabilizers such as cement, lime, and cement kiln dust (CKD) on their thermal behavior. This investigation, using two specific soil types designated as Soil A and Soil B, varied the concentration of additives from 0% to 15% over a 12-week duration. Employing a TLS-100 for thermal measurements, it was found that Soil A, with a 12.5% cement concentration, showed a significant 164.54% increase in thermal conductivity. When treated with 2.5% lime, Soil A reached a thermal conductivity of 0.555 W/(m·K), whereas Soil B exhibited a 53.00% decrease under similar lime concentration, reflecting diverse soil responses. Notably, a 15% CKD application in Soil A led to an astounding 213.55% rise in thermal conductivity, with Soil B recording an 82.7% increase. The findings emphasize the substantial influence of soil stabilization in improving the thermal characteristics of Hejaz soils, especially with cement and CKD, and, to a varying extent. This study is pivotal in identifying precise, soil-specific stabilization methods in Saudi Arabia’s Hejaz region, essential for developing sustainable engineering applications and optimizing construction materials for better thermal efficiency.
