Jan 14, 2020 · Biological approaches are emerging in the field of geotechnical engineering and techniques like microbial induced carbonate precipitation (MICP) have shown to be an effective means of effectively...

May 4, 2023 · In this context, the present paper reviews in detail the existing state-of-the-art and discusses the different proven and emerging biostabilization strategies/approaches/methods, that can be combined to serve as sustainable pathways for achieving anti-desertification, an important step towards developing resilient infrastructure. 1. Introduction.

Nov 22, 2021 · Field applications (upscaling) of bio-mediated treatment processes for soil stabilization pose various challenges that need to be addressed before implementation, viz., understanding soil and pore fluid interactions, controlled distribution of mediated calcite precipitation, and permanence of the cementation [184].

Oct 1, 2016 · MICP can be considered as a practicable technique that can improves soil-supporting new and existing structures and can be used in many geotechnical engineering applications, such as slope stabilization and subgrade reinforcement.

Jan 3, 2023 · Soil stabilization is a geotechnical modality that improves the physiochemical properties of the soil. Biological modality is an emerging method that attracts the scientific community for soil stabilization.

Apr 18, 2023 · In these techniques, bio-chemical activities, including bio-cementing, bio-clogging, bio-coating, and bio-encapsulation, are employed to stabilize soil particles. The present study aims to examine the impact of bio-stabilizers type and quantity on the geotechnical characteristics of soil for soil stabilization.

Jul 30, 2020 · The aim of this article was to review bioenzyme-based soil stabilization techniques with an emphasis on bioenzymes production, mechanism of soil stabilization and future challenges, and opportunities of the sector. Soils are stabilized to increase strength and durability or to prevent erosion and dust generation.

Jul 27, 2017 · In this study, the effect of one of the most commonly used biological stabilization techniques, namely microbial induced calcite precipitation on the shear strength of a swelling fine-grained soil has been studied by means of laboratory-scale tests and the influence of bacterial concentration as well as the chemicals used in the treatment ...

May 14, 2019 · This study investigates the effect of biological treatment by means of Bacillus sphaericus on the SWRC of both coarse-grained and fine-grained soil samples. Pore fluid pH, X-ray diffraction, and scanning electron microscopy tests are used to better delineate the mechanisms affecting biologically induced alterations of SWRCs.

Jan 4, 2016 · Plants play a pivotal role in soil stabilization, with above-ground vegetation and roots combining to physically protect soil against erosion. It is possible that diverse plant communities boost root biomass, with knock-on positive effects for soil stability, but these relationships are yet to be disentangled.
