Optimal Mixing Design and Field Application Protocol of Lightweight-Foamed Soils with Waste Fishing Nets

Gil-Lim Yoon, Sun-Bin Kim, Jinung Do

Lightweight-foamed soils are mixed soils with foam and cement to enhance the solidity and lightness of soils. Marine wastes, especially waste fishing nets, can be additives to reinforce the engineering properties of lightweight-foamed soils. In this paper, lightweight-foamed soils reinforced with waste …

Mineral Evaluation and Undrained Cyclic Shear Response of MICP-Treated Sand in the Presence of Magnesium and Sulfate

Jinung Do, Qianwen Liu, Brina M. Montoya, Mohammed A. Gabr

Microbially induced carbonate precipitation (MICP) has attracted considerable interest as an innovative technology that improves soil’s stiffness and strength via CaCO3 precipitation induced by microbial metabolic activity. Mg2+ and SO42− are known to inhibit CO3-based mineral precipitation. In this study, MICP was …

Effect of geocell height on behavior of sand under constant compaction energy evaluated by plate load testing in large-scale soil box

Yeon‐Tae Kim, Turab H. Jafri, Jinung Do

Abstract Geocell is a reinforcing material in civil engineering that creates cell structures with multiple bands filled with fill materials inside the cells, thereby providing a ground reinforcement effect. Due to the easiness of the construction and application, geocell is suitable for …

Preliminary Study on Application and Limitation of Microbially Induced Carbonate Precipitation to Improve Unpaved Road in Lateritic Region

Sojeong Kim, Yeon‐Tae Kim, Su‐Hyung Lee, Jinung Do

Some road systems are unpaved due to limited governmental finance and fewer maintenance techniques. Such unpaved roads become vulnerable during heavy rainy seasons following restrained accessibility among cities and traffic accidents. Considering the circumstances, innovative and cost-effective approaches are required for unpaved …

Effect of Salt Water on the Process of Microbially Induced Carbonate Precipitation

Jinung Do, Tae‐Hyuk Kwon

Microbially induced carbonate precipitation (MICP) is a bio-cementation process using microbes to hydrolyze urea and form carbonate-based minerals with the presence of Ca ion. This reaction produces bonding among soil grains and improves stiffness and strength of soils. The MICP implementation in …
