Seawater based MICP cements two/one-phase cemented sand blocks

Xiaoniu Yu et al.

Summary: Research has shown that the use of seawater-based microbial-induced carbonate precipitation technology can be applied in the construction of ocean islands and reefs. Different pH values of seawater-based UPB can induce calcium carbonate deposition at different times, with the strength and carbonate content of sand blocks cemented using the two-phase method being greater than that of the one-phase method.

Experimental Study on Optimization of Cementation Solution for Wind-Erosion Resistance Using the MICP Method

Monika Dagliya et al.

Summary: In this study, an environmentally friendly microbial-induced calcium carbonate precipitation (MICP) technique was used to reinforce desert sand using the stopped-flow pouring method. Experimental results showed that biotreatment with urease-producing bacteria and cementation solution significantly improved the strength of the sand and exhibited rock-like behavior.

Study on the performance of carbonate-mineralized bacteria combined with eggshell for immobilizing Pb and Cd in water and soil

Ting Wei et al.

Summary: Microbially induced carbonate precipitation (MICP) is an effective approach for remediating water and soil contaminated with heavy metals. In this study, the bacterial isolate UR21 showed high removal rates of Pb and Cd in water through MICP. In soil, the combination of UR21 with urea/eggshell waste reduced the extractable Pb and Cd while increasing soil enzyme activity and pH.

Micro-feature-motivated numerical analysis of the coupled bio-chemo-hydro-mechanical behaviour in MICP

Xuerui Wang et al.

Summary: In this study, a coupled bio-chemo-hydro-mechanical model (BCHM) was developed to investigate the effects of microbially induced calcite precipitation (MICP) on permeability reduction and stiffness improvement in soil. The model was able to capture the dynamic interactions between the bio-geo-chemical and mechanical processes, and consider the influences of microstructural aspects. It was concluded that the model could be potentially used as a designing tool for real MICP applications.

Microbially Induced Calcite Precipitation (MICP) for Stabilization of Desert Sand against the Wind-induced Erosion: A Parametric Study

Lei Hang et al.

Summary: Biocementation is a method to improve desert sand by forming a cemented layer to resist wind-induced erosion. The resistance of biocemented sand to erosion increases with higher treatment temperature and biocement solution concentration. However, the resistance decreases with more drying-wetting cycles.

Evaluation and Prediction for the Cementation Effect of MICP Based on Electrical Resistivity

Xiaohao Sun et al.

Summary: The study utilized electrical resistivity to evaluate and predict the treatment effects of microbially induced calcium carbonate precipitation (MICP). An empirical model was proposed to predict the relationship between electrical resistivity and soil properties such as porosity and unconfined compressive strength (UCS). The results showed that there are correlations between electrical resistivity and porosity, moisture content, and CaCO3 content in biotreated sand columns.

Summary: Microbially induced calcite precipitation (MICP) is a promising technique for geotechnical improvement by using bacteria-induced calcium carbonate precipitation. Experiments showed that treatment with specific bacteria under certain conditions can significantly enhance the strength and reduce the hydraulic conductivity of sandy soils.

A sample cell for the study of enzyme-induced carbonate precipitation at the grain-scale and its implications for biocementation

Jennifer Zehner et al.

Summary: Biocementation is a process based on either microbial-induced carbonate precipitation or enzyme-induced carbonate precipitation to create sustainable, consolidated porous material through the biomineralization of CaCO3 in a granular medium. A microscopy sample cell combined with confocal laser scanning microscopy allows real time monitoring of CaCO3 precipitation and pH, with the ability to characterize the precipitated crystals without sample disturbance. This approach offers a powerful tool for knowledge-based improvements in biocementation.
