Abstract
Treating sandy soil using a microbial induced calcite precipitation (MICP) process has been studied substantially in the past years. However, it is still a challenge to apply the MICP or other similar approach to treat fine-grained soil. In this paper, difficulties and challenges of using biocement to treat fine-grained soil such as marine clay are discussed. Different approaches adopted so far are reviewed. Some preliminary data are presented to illustrate the possibilities of improving the shear strength properties of clay using biotreatment or a MICP process through a so-call bioencapsulation method. However, the mechanisms behind the improvement in soil properties are yet to be fully understood. The cost-effectiveness is another issue that has yet to be addressed.
