“…The test results showed that sand, laterite, and clay soils require 4%, 6%, and 7.5% Portland cement type 1 to achieve UCS grades that meet road requirements in Malaysia. Research from [16] used high plasticity silt soil / MH (A-7-5) from Malaysia stabilized with Ordinary Portland Cement (OPC) CEM-I. The soil requires 6% with a curing time of 7 days sufficient to stabilize laterite soils to achieve a minimum UCS value of 0.8 MPa and a CBR value of 80%, following the Malaysian Public Works Department standard for low-volume roads and gravel road replacement.…”

The aggregate base course is important in the flexible pavement structure, requiring quality materials. In areas where quality material is difficult to find, local soil stabilization using cement is needed to obtain material to replace the aggregate base course. This study aimed to determine the optimum cement content in stabilizing sand-silty soil that meets the requirements specified in the General Specification of Highways 2018 for Road and Bridge Works and to find the effect of pH-soaking water. The research was conducted in the laboratory by testing the Unconfined Compressive Strength of soil cement using variations in cement content of 3%, 5%, 8%, and 10% of the dry weight of soil, soaking time of 3, 7, 14, and 28 days; and pH of soaking water (tap water with a pH value of 8, water with pH value of 4 (containing H2SO4), water with pH value of 9 (containing NaOH)). Cement content of 8% and 10% meets the minimum UCS value according to road specifications. The optimum cement content (which produces the UCS target specification value of 2353.60 kPa) is 9% on the seventh day. Soaking water with pH 4 and 9 decreased the UCS of soaking water with a pH value of 8. A soil cement base course can substitute an aggregate base course in areas with inadequate aggregate material with an 80% CBR value.

“…The region's expansive clays, sabkha soils, and oil-contaminated areas require innovative stabilization solutions to ensure construction safety and longevity. Studies on soil stabilization with cement and lime indicate that cement generally surpasses lime in enhancing soil strength and durability [32][33][34]. In Al-Hofuf's 'Hamrah', a soil mixture with 15% cement attained a maximum compressive strength of 6.3 MPa, notably higher than the 1.46 MPa achieved with 10% lime [32].…”

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.

Fine, expansive, and problematic soils cannot be used in fills or paving layers. Through additions to these soils, they can be converted into technically usable materials in civil construction. One methodology to make them viable for construction is through a stabilization process. Nevertheless, current methodologies regarding dosage based on compaction effort and the volumetric amount of binder used are unclear. Thus, this research describes cement-stabilized sedimentary silt's strength and durability properties from Curitiba (Brazil) for future application in paving. Splitting tensile strength, unconfined compressive strength, and loss of mass against wetting and drying cycles (W-D) were investigated in the laboratory utilizing greenish-gray silt (originating from one of the Guabirotuba Formation layers, Paraná) and high-early strength Portland cement- ARI (CPV). Utilized were cement concentrations (C) of 3, 5, 7, and 9%, molding dry unit weights (d) of 14, 15, and 16 kN/m3, curing periods (t) of 7, 14, and 28 days, and constant moisture content (w) of 23%. With an increase in cement concentration and curing time, the compacted mixes demonstrate an increase in strength, an improvement in microstructure, and a decrease in accumulated mass loss (ALM) and initial porosity (η). Using the porosity/volumetric cement content ratio (η/Civ), the lowest amount of cement required to stabilize the soil in terms of strength and durability was determined. The porosity/cement index provided an appropriate parameter for modeling the mechanical and durability properties, and a unique equation between the strength/accumulated loss of mass and the porosity/binder index was obtained for the curing times studied. Lastly, C = 5% by weight is the minimum acceptable amount for prospective subbase soil application. Doi: 10.28991/CEJ-2023-09-05-02 Full Text: PDF
