The troublesome soil that many geotechnical engineers encounter in the sector is clay soil. It presents a major danger to the foundations of light structures. Granular columns have proved beneficial in resolving foundation stabilisation and settling issues, making soft clay more appropriate for foundation building. This study aims to determine whether adding acrylonitrile butadiene styrene (ABS) to kaolin clay increases its shear strength. The physical, mechanical, and morphological properties of the materials used in this research (i.e., kaolin and ABS) must first be identified. The soft clay kaolin was strengthened with ABS columns and tested using the unconfined compression test (UCT) and the unconsolidated undrained test (UUT). The diameter of the columns used in this study was 8, 12, and 16 mm, while the penetration depth ratio used was 0.5, 0.75, and 1.0. The highest improvement in shear strength occurred at a height penetration ratio of 0.5 with values of 102.94%, 48.56%, and 50.02%. The UCT results demonstrated a decrease in the volume of the replacement ratio, followed by an increase in the height of the column. The UUT was conducted to evaluate the soft clay's shear strength when reinforced with an ABS column. The cell pressure used was 50, 100, and 200 kPa with the same column diameter specification as the UCT. The friction angle, υ, increased significantly from 8.92% to 18.21%. Furthermore, there was an improvement in cohesiveness, c, which increased from 4.54% to 45.45%. The results show that installing ABS columns improves the strength and compressibility of clay samples.

“…However, the friction angle has been slightly influenced by cement content. Moon et al [21] measured the compressive strength, ultrasonic pulse velocity (UPV), and shear wave velocity (Vs) of the sandcement mixtures containing low contents of kaolin particles up to 5%. According to the results of this research, the strength and stiffness of cemented sand mixture increased with increasing in fine content due to improving the density of the mixture with kaolinite particles.…”

“…Despite the various studies about the mechanical specifications of cemented sand or cemented clay mixtures, there is a lack of comprehensive investigations about the behavior of CSG mixtures in which the base soil is comprised of clayey or silty sands, and the previous research [21] was conducted on the CSG mixtures containing a very limited fine content (up to 5%) and one type of fine particle. This paper, therefore, aims to investigate the compaction, deformation modulus and strength of CSG mixtures enriched with various contents of bentonite and kaolinite powders in the presence of different cement contents.…”

The hardfill embankments are composed of cemented sand-gravel (CSG) mixtures. In some cases, however, sand and gravel used in the mixture contain fine-grained fraction. This paper aimed to study the mechanical behavior and microstructure of CSG mixtures in which the base soil contains fine-grained particles with different plasticity specifications. Various contents of kaolinite and bentonite were added to a sand-cement mixture with different cement contents and uniaxial strength and deformation modulus in the mixtures were measured at two curing ages. According to the results, in low cement mixtures, the mixture containing 10% of the additive exhibited the maximum strength and deformation modulus, regardless of the additive type. In a family of bentonite-containing mixtures with higher cement, the strength of mixtures decreased with increasing the bentonite content. However, the mixture with higher cement and 10% of kaolinite presented the best performance from in terms of strength and stiffness. Analyzing the mineralogy and SEM images of mixtures showed that the structure of base soil attained the best packing and a strong matrix was devolved inside the mixture with 10% of fine additive. Furthermore, the kaolinite particles in the mixture containing 10% kaolinite contributed to the hydration process of cement.

“…Moreover, many research works were carried out to test the CSA cement for ground improvement purposes under various conditions. The results of experimental and numerical studies proved the rapid strength gain property of CSA cement while comparing it with other binding materials [4,[10][11][12][13]. Furthermore, Jumassultan et al [14] investigated the effect of cyclic freezing and thawing on CSA-treated quartz sand, where CSA-treated sand has shown better performance with insignificant changes after freeze-thaw cycles.…”

The problem of weak ground conditions is currently of great interest, as with the rapid development of infrastructure, researchers are trying to cope with the improvement of problematic soil properties to build structures on it. In cold regions, the problem of weak soils is further exacerbated by freeze–thaw cycling. For the improvement of soil properties, the soil stabilization method using ordinary Portland Cement (OPC) is commonly applied, but it produces a significant amount of carbon dioxide emissions. Therefore, the purpose of this research study is to present laboratory testing results for the evaluation of soil treatment using Calcium Sulfoaluminate (CSA) cement that has a lesser carbon footprint. On stabilized soil specimens cured for 3, 7, and 14 days and subjected to freeze–thaw cycles, unconfined compressive strength (UCS) and ultrasonic pulse velocity (UPV) testing were performed. Samples were prepared at optimum moisture content using different cement content, 3%, 5%, and 7%. Applying the results from the UCS test, the strength loss/gain and resilient modulus of treated soil were obtained. The test results show that the strength and pulse velocity values decreased with the increase of freeze–thaw cycles. However, improvement in soil performance can be observed with the increase in cement content. Overall, the use of CSA as a stabilizer for silty sand would be useful to achieve sufficient strength of subgrade.
