Suffusion is a critical issue in geotechnical engineering. Despite extensive studies, the effect of soil specimen dimensions on suffusion remains unclear. In this paper, a coupled computational fluid dynamics and discrete element method (CFD-DEM) approach is employed to study the suffusion of gap-graded soils with varying aspect ratios, and the underlying physical mechanisms are discussed. The results indicate that as the aspect ratio increases, erosion degree, mechanical coordination numbers, and unevenness in the fines distribution decrease, while the likelihood of fine particles integrating into the soil skeleton rises. Before suffusion, specimens with lower aspect ratios show higher peak strengths. After suffusion, peak strength decreases with erosion degree. However, all specimens exhibit comparable residual strengths. The mechanism behind different suffusion behaviors in specimens with varying aspect ratios is primarily governed by their unique suffusion boundary conditions. Accounting for suffusion boundaries significantly modify erosion laws and eroded soil mechanics behaviors. A standardized specimen size is proposed to account for suffusion boundary effects, thereby minimizing errors attributed to variations in outlet sieve aperture sizes and inconsistencies in specimen dimensions. The results obtained highlight the influence of specimen size on suffusion, advancing our precise understanding of eroded soil behavior and furthering the development of phenomenological constitutive models.

“…So far, the long-term stability performance of modified soil subgrades is also a key issue. Due to rainfall or elevated water tables, the disintegration breakage of improved residual soils often leads to severe settlement and a decrease in the stability of the subgrade [25,26]. The water resistance of the treated subgrade filler is essential to the long-term service performance of the subgrade.…”

“…With respect to the stabilized soils, investigations into water stability have primarily emphasized two aspects: analyzing the concentration changes of cations (e.g., calcium ions, sodium ions, etc.) in the solution of stabilized soils after leaching [8,24,38] and assessing the weakening of strength properties resulting from water immersion [9,26,39]. Little literature has been found on disintegration characteristics for stabilized soils; moreover, there is a lack of relevant disintegration models to describe the evolution of disintegration characteristics of stabilized soils, which can be useful for the design of subgrade engineering.…”

Urban construction has generated substantial amounts of waste soils, impeding urban ecological development. With the aim of promoting waste recycling, waste soils possess a high potential for sustainable utilization in subgrade construction. However, these waste materials exhibit inadequate engineering properties and necessitate stabilization for an investigation into their long-term performance as subgrade filling materials. Initially, a thorough assessment and comparison were conducted to examine the key mechanical properties of lime- and cement-stabilized soils with mixed ratios (total stabilizer contents ranging from 2% to 8%). The results indicated that these soils met the requirements of subgrade materials except for the 2% lime-treated soil. Subsequently, to reveal the improvement in water resistance of stabilized waste soil (e.g., under conditions of rainfall or elevated groundwater table), the effects of soil densities and stabilizer contents on the disintegration characteristics were investigated using a range of disintegration tests. An evolutionary model for the disintegration ratio of stabilized soils was then developed to predict the process of disintegration breakage. This model facilitates the quantification of the lower disintegration rates and elevated disintegration time attributed to higher levels of compactness and stabilizer contents during a three-stage disintegration process. This enhances the understanding and evaluation of sustainable applications in stabilized waste soils used as subgrade filling materials.

“…The use of geopolymer materials as soils stabilizers has been widely studied and results of such past studies indicate that geopolymers could be used as an effective soil stabilizer. The inorganic types cement (Abdulkareem, 2020;Abdullah et al, 2019;Sharma et al, 2019;Vitale et al, 2020), lime (Abdullah et al, 2020b;RezazadehEidgahee et al, 2020;Saberian, 2020), fly ash (Dheyab et al, 2019;Jahandari et al, 2019;Khasib and Daud, 2020;Tan et al, 2019;Teing, 2019;Wen et al, 2019;Yaghoubi et al, 2019 ), organic polymers (Anonymous; Amiri and Emami, 2019;Chang and Cho, 2019;Elandaloussi, 2019;Pradhan et al, 2019) and their mixtures (Kuang, 2019). These inorganic stabilizing agents are mainly used in non-ecological soil stabilization.…”

The strength of a fine-grained lateritic soilfrom three (3) different localities on Abuja – Lokoja road where road failure happen was treated with rice husk ash (RSA), cement andsodium silicate activator (SSA), with varying percentage examined by means of Atterberg, Compaction and triaxial shear tests. The addition of optimum cement with additives changes laterite sample of plasticity index (PI) into non-plastic and resulted in a minimum of 11.90 % reduction in PI of lateritic soil which led to the belief that additives decreases plasticity of soils, and this is an advantage, because reduction in PI contents indicates animprovement.Thecompaction characteristics of the natural lateritic soils were altered with the addition of optimum contents of OPC with each of RHA, KCP and SSA. The MDD of cement-stabilized residual soil slightly increased with the increase in cement content, whereas by adding RHA, KCP and cement, the OMC is decreases steeply. Also, CBR results shows that CBR of the soil-cement-SSA content increases upon adding sodium silicate activator content up to 4% SSA content before the value experiences reduction at much higher SSA content. But, theRHA-treated residual soils decrease the CBR value from 6% upwards. This, again, alludes that RHA alone is not suitable as stabilizer.
