Sandy materials with or without a non-plastic fines content, including sand recovered from Urayasu City after the 2011 Great East Japan Earthquake, were employed and solidified with CaCO3 produced by a bacterial species named Sporosarcina pasteurii in a study. The solidified materials were prepared in a triaxialcell and then subjected to undrained cyclic loading. The results were analyzed to provide insight into the effectiveness of MICP to sand with a non-plastic fines content in mitigating the liquefaction potential.
