Data on Experimental Investigation of PVA Fiber-Reinforced MICP Treatment for Improving Dispersive Soil Properties

This dataset contains comprehensive experimental data on the enhancement of dispersive soil properties using the PVA fiber-reinforced microbial-induced calcium carbonate precipitation (MICP) technique. The dataset includes raw and processed data from laboratory tests evaluating soil dispersivity, unconfined compressive strength (UCS), split tensile strength (STS), disintegration resistance, calcium carbonate (CaCO3) content, and stress-strain behavior. Additionally, it features chemical environment monitoring data, microstructural analysis using SEM and EDS, and mineralogical analysis through X-ray diffraction (XRD). This dataset provides a detailed foundation for understanding the mechanisms underlying the improvement of soil dispersivity, as well as its engineering applications in erosion control and ecological restoration.
