Bio-remediation of desiccation cracking in clayey soils through microbially induced calcite precipitation (MICP)

Abstract
Desiccation cracking is a common natural phenomenon in clayey soils, considerably degrading their mechanical and hydraulic properties. Typical remediation methods are associated with high labor costs, high maintenance costs, or the usage of environment-unfriendly chemicals. Microbially induced calcite precipitation (MICP) has emerged as a green and sustainable soil improvement technique. The application of MICP in clayey soils remains poorly investigated due to the presence of microscopic pores among clay soil particles that restrain the free passage of bacteria. In this study, we carry out cyclic wetting-drying tests to characterize the effect of MICP on the desiccation cracking behaviors of clayey soils.
