Spatial Distribution of CaCO3 in Biocemented Sandy Slope Using Surface Percolation | Journal of Materials in Civil Engineering
Abstract The microbial-induced carbonate precipitation (MICP) technique has been increasingly employed for erosion mitigation and stabilization of sandy slopes. Biocementation can improve the strength and stiffness of unsaturated sand. In this study, the performance of a new biogrouting method (i.e., surface percolation) for sandy slopes under unsaturated conditions was investigated. Model-scale laboratory tests were conducted on…
