MICP incorporated biopolymer to mitigate wind erosion of sand

Scientific Reports
In this study, the Microbially Induced Carbonate Precipitation (MICP) technique was integrated with four distinct biopolymers to evaluate the wind erosion resistance and durability of desert sand soil in Kashi, Xinjiang. The samples were analyzed using Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), and X-ray Diffraction (XRD).

Comparison of Gypsum and MICP in Stabilizing an Expansive Soil

International Journal of Innovative Research in Science Engineering and Technology
ABSTRACT Expansive soils are considered problematic for civil engineering applications due to their low strength, high compressibility, and poor bearing capacity, which limit their use as foundation or pavement subgrade materials. To overcome these limitations, this study investigates the stabilization of expansive soil using gypsum and Microbially ...
