摘要
Microbially Induced Calcite Precipitation (MICP) is a relatively new soil improvement technique that has been extensively studied during the last two decades. Most of these studies have been performed in saturated conditions and only few papers deal with non-saturated conditions. In this study, we investigate two injection protocols with or without resting periods between treatment steps. The results of unconfined compression tests performed on treated samples, as well as the measurement of the calcite contents, lead to the conclusion that the resting periods improve the stiffness of the samples and the calcite content.
