Mehran University Soil Stabilization Research Proposal: MICP Method

This research proposal outlines a study focused on eco-friendly soil treatment and stabilization using Microbial Induced Calcite Precipitation (MICP). The study aims to establish effective techniques to improve soil properties, focusing on the application of Sporosarcina pasteurii bacteria to induce calcite precipitation within the soil matrix. The methodology involves laboratory experiments to analyze the impact of varying concentrations of bacteria (1% to 3%) on soil parameters such as shear strength and maximum dry density. The research includes the preparation of nutrient and reagent solutions, sample preparation, and testing procedures like modified Proctor tests and direct shear tests. The results will be compared to natural soil properties to determine the effectiveness of MICP in enhancing soil characteristics, with the goal of providing sustainable alternatives to traditional soil stabilization methods. The proposal also includes details on soil classification and the specific experimental procedures performed to analyze the soil samples before and after the MICP treatment. The study is designed to contribute to more sustainable construction practices by improving the engineering properties of weak soils.
