Abstract:
Biogrouting is a new ground improvement method based on Microbial Induced Calcite Precipitation (MICP). MICP involves formation of calcium carbonate precipitate within the soil mass after injecting microbes and cementation reagent including urea and calcium chloride dihydrate. Non-ureolytic bacteria Bacillus subtilis is used in this study which accelerates the CaCO3 formation through addition of nucleation sites. Improvement in shear strength, permeability, compaction and plasticity characteristics of Cochin Marine Clay (CMC) by varying count of bacteria (1 x 107, 1 x 108 and 1 x 109 cells/ml), concentration of cementation reagent (0.5 M, 1 M and 2 M) and treatment duration (10, 20 and 30 days) was studied and reported. Greater improvement is observed at 109 cells/ml, 1 M and at 30 days. Improvements has reduced at higher concentration of cementation reagent. Influence of treatment duration in soil improvement was observed. The calcite precipitation was confirmed by set of test tube experiments and XRD analysis.
