“…For instance, a mere 2.5% addition of CKD elevated the thermal conductivity (K) value from 0.251 to 0.427 W/(m•K), representing a substantial increase of 70.12%. This enhancement in thermal conductivity is attributed to the pozzolanic reaction of CKD in the soil, which leads to increased density and improved soil structure, as evidenced by the significant increase in density, CBR, and UCS observed in CKD-stabilized soils [67]. This pozzolanic reaction, crucial for soil stabilization, results in the bonding of dispersed soil particles, enhancing the soil's thermal properties [68].…”

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.

“…The ability to use the CKD as an alternative material for cement was studied by Mahdi et al ( 2018) [25]. They concluded that using 20% of CKD increased CBR value, optimum moisture content, density, and shear strength of type (B) subbase soil.…”

The engineering problems of problematic soils are mainly related to their mechanical, physical, and mineralogical properties. Extensive efforts have been directed to mitigate damages that may happen for structures constructed on, or in these soils' types. Both conventional materials (e.g. cement, lime, etc.), chemical and produced materials were blended, mixed, or added to soils to improve their geotechnical properties. In the last years, different additives from the wastes of industrial processes have been adopted in engineering researches to improve soils. This paper reviews different industrial wastes materials (e.g., fly ash, blast slag, rice husk ash) as soil stabilizers, where the use of them has economic and engineering benefits. The effect of these materials on physical properties, compaction characteristics, compressive strength, and bearing ratio of soils have been presented, studied, and discussed. The contents of these materials are widely varied from reference to reference and reach a maximum value of 50%. These materials cause reduction in Atterberg limits and swelling potential to different degrees. For some soils, MDD and OMC increase with the addition of these materials, and verse versa. Almost, these materials cause an improvement in soils' strength and CBR. However, some wastes reveal more efficiently to improve the soil

There are large deposits of waste materials from various industrial or building activity all over the world. Out of this enormous quantity of waste, a little amount gets recycled, while the rest is dumped in vulnerable places. This paper examines the potential use of waste materials in subbase, including recycled chips derived from waste polyethylene terephthalate plastics and cement kiln dust resulting from Portland cement industry as by-product. Samples were formed by blending fractions of 0, 4, 6, and 8% recycled chips with or without 3% cement kiln dust (CKD) by the required weight of subbase soil. The influence in terms of strength was evaluated using CBR values, which exhibited descending values with increasing recycled plastics chips contents. While the addition CKD significantly enlarged the values. Based on the CBR values 4% recycled plastics chips with 3% CKD blend is commended for subbase layer in roads construction.
