“…Therefore, the UCS and UU samples were prepared with height and diameter equal to 76mm and 38mm, respectively, to prevent the impact of aspect ratio (height/diameter) [44]. The loading speed was equal to 1.52mm/min to simulate soil behaviour under quick loading [45]. All the samples were prepared at OMC and MDD.…”

Lateritic soil resulting from weathering, particularly the chemical weathering process of rocks, is found widely in tropical and subtropical countries such as Malaysia, Thailand, Singapore, and Brazil. The characteristics of this residual soil depend on many factors, including weathering degree, chemical compositions, and laterization degree, indicating their varying properties from one place to another. Thus, it is essential to explore their characteristics before using them as a construction material for a particular structure. In this paper, a lateritic soil sampled from Universiti Teknologi Malaysia has been explored in terms of grain size distribution (GSD), Atterberg limits, specific gravity, compaction, unconfined compressive strength (UCS), unconsolidated undrained (UU) test, FESEM, and EDX. The obtained results indicated that the soil is classified as plastic silt (MH) and A-7-5 according to USCS and AASHTO methods, respectively. The optimum moisture content (OMC) and maximum dry density (MDD) were obtained 28 % and 1.39 g/cm3, respectively, based on the standard compaction method. The unconfined compressive strength (UCS) is 200.75 kPa, whereas, in the unconsolidated undrained (UU) test, the deviator stress is equal to 449.4 kPa, 529.3 kPa, and 674 kPa for 50, 100, and 200 kPa, respectively. The total friction angle and undrained cohesion are 25.69° and 115.82 kPa, respectively. According to the FESEM results, the matrix microstructure was detected for the soil. The O, Al, Si, and Fe were detected as primary chemical elements in the soil. The results of this study can help the practitioners to classify the laterite soil and decide based on its characteristics.

Utilizing waste materials to improve soil properties can result in cost savings and environmental benefits. This study aims to determine the effect of adding agricultural wastes like rice husk ash (RHA), rice husk (RH), and groundnut shells (GS) to clayey sands from Mysore district, India. The study focused on the undrained strength, permeability and volume change behaviour of soils mixed with RHA, RH and GS. The soil samples were mixed with varying amounts of RHA (5%, 10%, 15%, and 20% by weight) and RH-GS (1%, 2%, 3%, 4%, and 5% by weight) and cured for 1, 7, 14 and 21 days. These blended specimens were then used to determine the maximum dry density (MDD), optimum moisture content (OMC) and unconfined compressive strength (UCS). The soil mixture containing 5% RHA and 4% (RH + GS) yielded optimal results in the UCS test. Further tests, including unconsolidated undrained (UU) triaxial, permeability and consolidation tests, were conducted on the parent soil and the soil composite with 5% RHA and 4%(RH + GS). From the undrained test, the strength increased for the soil admixture, with a reduction in the cohesion and an increment in the friction angle, compared to that of the parent soil. The experimental results also showed improvement in the permeability and consolidation characteristics of the blended soil.

“…Expansive soils demonstrate significant volumetric expansion and contraction in response to variations in seasonal moisture levels. The challenges associated with the variation in volume of global entities have garnered significant attention [3][4][5]. Moreover, expansive soils pose significant structural and geotechnical difficulties in various tough scenarios across the globe.…”

Soil stabilization is critical in civil infrastructure, acting as a cornerstone for sustainable and resilient building practices. It enables the construction of strong foundations capable of withstanding enormous loads and adverse conditions, assuring the safety and lifespan of structures such as buildings and roads. The utilization of industrial by products for enhancing the qualities of locally expanding soils has become increasingly popular, mostly due to its low carbon emissions and cost-effectiveness. The present investigation focused on the effect of the addition of Ground Granulated Blast furnace Slag (GGBS) and Geopolymer solution to expansive soil in order to reduce the erosion of slopes. Unconfined compressive strength tests were performed and found that 10% GGBS is the optimum amount for stabilization. SEM studies were conducted to know the microstructure before and after stabilization. The study determined that the rate of rainfall erosion on the stabilized slope was lower compared to the untreated soil, and the load-carrying capacity of the stabilized slope was much greater.
