Enhancing Strength of EICP-Treated Sand Using a Protein-Based Additive
Background Effective ground improvement methods are essential for optimal utilization of land, whether they be roads, embankments, dunes, or slopes. Conventional methods using compaction, pile insertion, and cement-soil mixing provide adequate stability but have several major drawbacks. They are often expensive, time-consuming, require specialized...

Optimal Soil Cementation By Agricultural Urease For Use In Aqueous & Non-Aqueous Environments
Civil and geotechnical engineers must fortify sandy soil in order to build durable structures on loose terrain. Effective soil cementation can be achieved by microbial induced carbonate precipitation (MICP), a process using microbes to generate urease enzymes that catalyze calcium carbonate precipitation. However, MICP is limited by the large size of...

Enhancing Biocementation Using Hydrogels
Enzyme-induced carbonate precipitation (EICP) is a technique used for soil stabilization. EICP cements soil particles together using urease enzymes to precipitate calcium carbonate in a water-based solution. EICP may be used as a means of improving the bearing capacity of soils, preventing erosion, and mitigating the potential for earthquake‐induced...
