Crack remediation in mortar via biomineralization: effects of chemical admixtures on biogenic calcium carbonate
Limited research on biomineralization in cement-based systems suggested that self-healing of surface cracks could be obtained by triggering biogenic calcium carbonate (CaCO3) precipitation within the cracks. While this is ...
Biomineralized cement-based materials: impact of inoculating vegetative bacterial cells on hydration and strength
Biomineralization in cement-based materials has become a point of interest in recent years due to the possibility that such an approach could be used to develop a self-healing cement-based system. The objective of this ...
Use of corn-steep liquor as an alternative carbon source for biomineralization in cement-based materials and its impact on performance
Early age microcracks are generally the primary cause for a decrease in service life of cement-based structures. Recent studies suggested that it might be possible to develop a smart cement-based material that could self-heal ...
Biomineralization in self-healing cement-based materials: investigating the temporal evolution of microbial metabolic state and material porosity
(American Society of Civil Engineers, 2017)
The potential for self-healing of concrete via biomineralization processes in which microorganisms influence mineral precipitation is promising. To embed microorganisms within a cement-based material, key challenges are ...
Use of pre-wetted lightweight fine expanded shale aggregates as internal nutrient reservoirs for microorganisms in bio-mineralized mortar
Interest in developing bio-based self-healing cement-based materials has gained broader attention in the concrete community. One of challenges in developing bio-based self-healing cement-based materials is that cell death ...
Impact of air entraining admixtures on biogenic calcium carbonate precipitation and bacterial viability
The applications of self-healing in cement-based materials via biomineralization processes are developing quickly. The main challenge is to find a microorganism that can tolerate the restricted environment of cement paste ...
Immobilization of bacterial cells on natural minerals for self-healing cement-based materials
(Frontiers Media, 2021-04-13)
Recent research in the field of concrete materials showed that it might be possible to develop a smart cement-based material that is capable of remediating cracks by Microbial-induced calcium carbonate precipitation (MICP). ...
Çimento-esaslı harçlarda kendiliğinden iyileşmenin sağlanması için 2 bileşenli biyolojik katkı maddesinin geliştirilmesi
(Gazi Üniversitesi, 2021)
Purpose: Throughout the literature, studies showed that among several alternatives such as diatomaceous earth (DE), metakaolin, zeolites and expanded clay could be suitable for protection of the bacteria based on their ...
