Improved methods, properties, applications and prospects of microbial induced carbonate precipitation (MICP) treated soil: A review

Biogeotechnics, Journal Year: 2024, Volume and Issue: 3(1), P. 100123 - 100123

Published: July 18, 2024

Soil improvement is one of the most important issues in geotechnical engineering practice. The wide application traditional techniques (cement/chemical materials) are limited due to damage ecological environment and intensify carbon emissions. However, use microbial induced calcium carbonate precipitation (MICP) obtain bio-cement a novel technique with potential induce soil stability, providing low-carbon, environment-friendly, sustainable integrated solution for some problems environment. This paper presents comprehensive review latest progress based on MICP strategy. It systematically summarizes overviews mineralization mechanism, influencing factors, improved methods, characteristics, current field status MICP. Additionally, it also explores limitations correspondingly proposes prospective applications via approach improvement. indicates that utilization different environmental calcium-based wastes combination materials conducive meeting market demand. Furthermore, we recommend encourage global collaborative study practice view commercializing future. purports provide insights engineers interdisciplinary researchers, guidance future applications.

Enhancing concrete crack healing: Revealing the synergistic impacts of multicomponent microbial repair systems

Case Studies in Construction Materials, Journal Year: 2024, Volume and Issue: 21, P. e03402 - e03402

Published: June 13, 2024

Small cracks in concrete can develop into larger cracks, reducing the service life of structures. Therefore, early prevention fine crack progression is crucial. In this study, a multimicrobial system composed Bacillus megaterium and Saccharomyces cerevisiae was used to repair its efficiency evaluated through fracture healing observations, permeability tests, acoustic time value detection, unconfined compressive strength tests. Additionally, scanning electron microscopy, energy dispersion spectroscopy, X-ray diffraction, Fourier-transform infrared spectroscopy were analyze mechanism multicomponent microbial system. The results showed that when ratio S. B. 30 %:70 %, calcium carbonate (CaCO3) yield increased by 10 mineralization deposition effect optimal. Under synergistic action two microorganisms, proceeded quickly pore structure within became denser, significantly improving rates sample pulse velocity. For 1.5 mm width, 63 % 35.12 respectively. velocity reduced from 140 µs 65 µs. filler mainly CaCO3 crystals 5–10 µm size, total content as high 39.5 which higher than single component (36.1 %). indicate maintains precipitation activity high-strength alkaline environment produces denser deposits, indicating good ability. These properties improve overall performance concrete. This study confirms strong potential systems for efficient, cost-effective, environmentally-friendly repair.
