“…The combination of traditional stabilizers like cement and lime with innovative materials such as sodium silicate, Oil Shale Ash (OSA), and Ordinary Portland Cement (OPC) has shown promising results in enhancing the mechanical properties, durability, and thermal insulation of soil [42,43]. These combinations yield a resilient and long-lasting construction material, characterized by superior compressive strength, low water absorption, and minimal shrinkage.…”

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 quality of bricks depends greatly on the soil type, compaction force, type and percentage of stabilizer, production and curing procedures, and weather (Wells, 1993). Cement is the most prevalent stabilizer associated with sandy soil CSEB, and the brick is still considered green with up to 10% by weight because cement contributes to its strength and durability ( UN-Habitat, 2009;UN-Habitat, 2012;Bogas et al, 2019;Edris et al, 2021;Kasinikota and Tripura, 2021). Although recent researches has experimented with natural materials, as well as agricultural and industrial waste to minimize or replace cement (fly ash, polymers, geopolymer binders, sugarcane fibers) (Omar Sore et al, 2018;Idriss et al, 2022;Tchouateu Kamwa et al, 2022;Nadia et al, 2023), cement was selected in the production of EH bricks.…”

This is because it is the most tested and utilized stabilizer associated with CSEB production, its commercial availability and lower price in Egypt, higher strength results, and most importantly its suitability to sandy soil and mass-production ( UN-Habitat, 2009;UN-Habitat, 2012;Bogas et al, 2019;Edris et al, 2021;Kasinikota and Tripura, 2021).…”

As a response to rising housing prices and the high cost of materials in the building and construction industry, a rural prototype house (the Ecofordable House) was built with alternative technologies. The house is located in the western desert zone of Giza, Egypt, and features enhanced vernacular technologies with local materials. Interlocking compressed stabilized earth brick walls, partially reinforced, jack arch and funicular shell roofs, and date palm midribs were employed in an attempt to reduce the usage of steel, fired bricks, cement, and imported wood. The present research evaluates the house’s construction cost-effectiveness and affordability through detailed real-world data and comparisons of material quantities, labor, and costs with those of conventional methods. The “price-to-income ratio” is used as an indicator of affordability. According to the findings, walls cut costs by half, roofs by a quarter, and midribs by two-thirds; the alternatives combined saved 45%, and the house saved a quarter of the cost after adding common expenses. Moreover, less than one-third of steel, fired bricks, and cement were utilized. In the Egyptian context of government-built houses, the prototype would be affordable for most Egyptian income brackets while the conventional house was expensive for the lowest three. The findings provide empirical support for the economic advantages of enhanced vernacular technologies as alternatives and address residential affordability in similar contexts.

“…This involved utilizing cement as a stabilizing agent to create an earth-based mortar with an optimal recipe. Earthbased mortar stabilized with cement fulfilled the mechanical, conservation, durability, and technological requirements [10][11][12][14][15][16][17][18][19]. Investigations have been undertaken to investigate the stabilization of soil-based materials with cement commonly employed as a stabilizer.…”

The investigation into earthen construction technologies and materials is now acknowledged as a crucial area requiring further research. Earthen mortars are prevalent in both modern and traditional construction due to the abundance of earth material, their favorable thermal properties, and their low embodied energy. The objective of this study is to support the use of natural materials collected from north Jordan to enhance the mechanical properties and durability of mud mortar. The local soil was stabilized using Oil Shale Ash (OSA), Ordinary Portland Cement (OPC), and lime for producing mud mortar. Particle size analysis, plastic limit, liquid limit, XRD, and XRF were applied to assess the geotechnical characterization and mineral composition of the earthen stabilizers and local soil. In order to examine the mechanical properties (specifically compressive strength) and durability characteristics (such as water absorption and shrinkage) of mud mortar, a total of 8 mixtures were prepared. One of these mixtures served as a control, while the others were created by substituting soil with varying proportions of OSA, cement, and lime. The results show that the mud mortar contained 10% OSA and 10% cement, which exhibited the highest compressive strength. Moreover, an increase in the proportion of OSA in the soil led to a decrease in absorption and linear shrinkage, indicating that OSA is an effective stabilizing agent for mud mortar.
