Shear response of bio-cemented sands with varying particle sizes under different stress paths

Microbial induced calcium carbonate precipitation (MICP) is a bio-mediated technique that may be used to improve the strength and stiffness of soils. Various parameters affect the behavior of MICP-cemented sand, and their effects must be explored before upscaling the MICP treatment technique. The data herein present the shear response of three types of sand (Ottawa 20-30, Ottawa 50-70, and Nevada) sheared in drained triaxial under three effective confining pressures (10, 100, and 400 kPa) at four levels of cementation (untreated, light, moderate, and heavy) subjected to four different stress paths (axisymetric compression, radial extension, constant p, and constant q).
