Microbially induced carbonate precipitation for soil improvement: factorial analysis, shear testing and characterisation

Key Points

• To investigate the effects of microbially induced carbonate precipitation on soil properties.
• Conducted factorial analysis to assess carbonate precipitation effects.
• Performed shear testing to evaluate soil strength enhancements.
• Characterized soil properties before and after microbial intervention.
• Increased soil strength observed following carbonate precipitation.
• Improvement in soil stability was correlated with higher microbial activity.
• Factorial analysis revealed significant interactions between microbial conditions and soil improvements.
