“…On the other hand, the trend of lateritic soil stabilised with 9% cement and 12% cement at 7-day curing is completely different under cyclic wetting-drying cycles. Similar to previous studies that showed the increasing trend of UCS under certain wet-dry cycles [38,74,75], in the current studies, the UCS of specimens stabilised by 9% and 12% cement increases with increasing wetting-drying cycles, indicating the high effectiveness of stabilised soil over time. In other words, the high cement content results in a high amount of hydration products (CSH, CAH) in the presence of water, thus resulting in increased compressive strength rather than strength degradation over wet-dry cycles.…”

“…7. The results obtained are consistent with the findings of [38], in which the compressive strength of cement stabilised low plasticity clay (CL) increased with increasing cyclic wetting-drying cycles. Besides, the current findings can be supported by the results of another study [72] in which the 3% treated soil illustrated a slight disintegration while stabilised soil with more than 3% cement showed a stable condition after submerging for 72 h into the water.…”

“…For high-cement content, the 5 h immersing and 42 h drying work as curing time, resulting in increased strength after each w/d cycle. Overall the findings of this research can be supported by previous studies' results [38,49,75,76]. In the previous studies, the UCS of stabilised soils showed an alternate increase and decreased trend during wetting-drying cycles.…”

“…In the previous studies, the UCS of stabilised soils showed an alternate increase and decreased trend during wetting-drying cycles. For instance, a previous study by Aziz et al [38] yielded a sudden increase of UCS after the first wet-dry cycle and an alternate increase and decrease of UCS for the rest of the wet-dry cycles. It is noteworthy that an overall increase of UCS of stabilised soil under repeated wet-dry cycles has been recorded for cement-stabilised soil [38].…”

“…Cement is widely used because of its advantages, such as low cost, remarkable integrity and strong water stability [37]. Furthermore, [38] mentioned that lime and cement are used widely because of their abundant availability. In summary, the cost, sufficient mechanical characteristics and availability make cement more common in geotechnical projects [39].…”

Evaluation of cement stabilised residual soil on macro- and micro-scale for road construction

et al. 2022

Lateritic soil is a kind of residual soil widespread in tropical countries. This soil usually possesses acceptable engineering properties to be laid under the construction projects. However, it needs treatment for transportation infrastructure such as railway and road subgrade and embankment, particularly when it is in fine-grained form. Thus, cement, one of the very common stabiliser agents in soil stabilisation, was selected to study its influence on lateritic soil at macro- and micro-levels. In order to achieve this goal, UCS, durability, FESEM and EDX tests were conducted. The results obtained indicate that the UCS increase occurs with an increase in cement content and curing time. It was also found that the shear modulus increases with cement content and curing time. The durability test results disclosed that 3% cement is not enough for soil stabilisation when used for projects in the areas subjected to cyclic wetting-drying cycles. The durability test results revealed that the UCS decreased for specimens treated with 6% cement, while on the other hand, the UCS increased for samples treated with 9% and 12% cement. The FESEM results revealed that the soil micro-structure changed with the addition of cement and curing time. The EDX results presented the chemical elements change upon adding cement and increasing curing time. Overall, it was found that cement-stabilised residual soil can be used for road construction. However, the cement percentage needed to stabilise residual soil differs depending on the standards.
