Retarding effect of concentration of cementation solution on biocementation of soil by Lai, Han-Jiang, Cui, Ming-Juan, Wu, Shifan, Yang, Yang, Chu, Jian

“…The retarding effect will dominate increasingly when CCS is higher than 1.0 M and the amount of calcium carbonate precipitation will reduce for the given amount and type of bacteria used in this study and become zero with CCS of 2.5 M. For the same calcium carbonate content, the unconfined compressive strength is greater for sand treated using a lower CCS as the contribution to the bonding strength by the calcium carbonate generated under a lower CCS is greater than that under a higher CCS.…”

Large-scale model testing of high-pressure grouting reinforcement for bedding slope with rapid-setting polyurethane by Zhang, Zhichao, Tang, Xuefeng, Liu, Kan, Ye, Longzhen, He, Xiang

“…Bedding slope is a typical heterogeneous slope consisting of different soil/rock layers and is likely to slide along the weakest interface. Conventional slope protection methods for bedding slopes, such as retaining walls, stabilizing piles, and anchors, are time-consuming and labor- and energy-intensive. …”
