| The study presented herein highlights the significance of microstructural analysis in understanding the behavior of collapsible soil and the effects of textile sludge treatment. The investigation employed SEM, EDAX, FTIR, and XRD techniques to analyze the microstructure of collapsible soil, textile sludge, and soil mixed with 24% textile sludge. The results indicate that the main cause of soil collapse is the weakening and rupture of calcium carbonate bonds, which are responsible for maintaining the soil structure under loading and saturation conditions. SEM analysis revealed the presence of large bracket-shaped pores on the soil surface, which contribute to its high susceptibility to collapse. The inclusion of textile sludge in the soil mixture demonstrated promising effects in reducing the soil's collapse potential. This can be attributed to the aggregate shape of the sludge particles, as well as their high specific surface area and the presence of abundant pozzolanic materials. These properties facilitated the formation of strong cementitious bonds between soil grains, leading to improved mechanical properties. Furthermore, the post-treatment microstructural analysis revealed that the addition of textile sludge resulted in the filling of pores with sludge particles, transforming the soil from a loose structure to a denser one. This densification further enhanced the stability and mechanical strength of the treated soil. Overall, the study emphasizes the importance of microstructural analysis in elucidating the mechanisms behind soil collapse and the beneficial effects of textile sludge treatment. By understanding these microstructural changes, researchers and practitioners can develop cost-effective and sustainable approaches for the disposal and repurposing of textile sludge in civil applications, contributing to environmental sustainability and mitigating the challenges associated with industrial waste disposal. | ||||
