The self-healing bioconcrete, or bioconcrete as concrete containing microorganisms with capacities, presents a transformative strategy to extend the service life of structures. This technology harnesses biological capabilities specific microorganisms, such bacteria and fungi, which are integral material's capacity autonomously mend cracks, thereby maintaining structural integrity. review highlights complex biochemical pathways these organisms utilize produce healing compounds like calcium carbonate, how environmental parameters, pH, temperature, oxygen, moisture critically affect repair efficacy. A comprehensive analysis recently published peer-reviewed literature, contemporary experimental research forms backbone this focus on microbiological aspects process. assesses challenges facing including longevity microbial spores cost implications for large-scale implementation. Further, attention is given potential directions, investigating alternative agents optimizing environment support activity. culmination investigation call action integrating in construction broader scale, realizing its fortify infrastructure resilience sustainability.

Concrete is prone to cracking over time, leading the deterioration of concrete structures. Using biomineralization capabilities bacteria, cracks in can be remediated favorable conditions. In this study, Bacillus subtilis spores were immobilized three different healing agents, namely lightweight expanded clay aggregates (LECAs), polyvinyl acetate (PVA) fibers, and an air-entraining admixture (AEA). spores, with a turbidity equivalent 4 McFarland standard, used dosages, 0.01, 0.1, 1% (by weight) cement. Based on dosage, groups developed each group consisted total nine mixes, which differentiated based method delivery bacterial spores. The specimens pre-cracked after 7 days, using embedded steel rod, being post-tensioned universal testing machine. self-healing efficiency was evaluated ultrasonic pulse velocity surface crack analysis, ImageJ software, precipitate analyzed microstructural tests, scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy analysis. results verified that improved increase dosage curing time. LECAs proved promising carrier, by accommodating nutrient media period 196 days. PVA fibers helped bridging provided nucleation sites for enhanced calcite precipitation. Similarly, AEA also encapsulating sealing up 0.25 mm, when conjunction LECAs. Furthermore, tests formation as product within bioconcrete. study offer valuable insights construction industry, highlighting ability bacteria reduce structures promoting sustainable approach minimizes need manual repairs, particularly hard-to-reach areas.
