Evidence date ·How microbial activity can help carbonate minerals form in concrete
Review or Meta-AnalysisTracked over timeA 2026 review links microbial mineral formation to self-healing concrete and highlights challenges in scaling up, long-term stability, and safety.
-
Evidence date ·How microbes and adjusted seawater could make biocement
Review or Meta-AnalysisTracked over timeA 2022 proposal uses electrically adjusted seawater, cyanobacteria and carbonate precipitation to make biocement, with modeled water and reactor demands.

Evidence date ·How one bacterial application filled small mortar cracks
Peer-Reviewed PaperTracked over timeIn a 35-day laboratory mortar test, one bacterial treatment filled small cracks and limited early water entry; its genome identifies candidate mechanisms.
-
Evidence date ·How a soil bacterium changed laboratory mortar strength while calcium set the terms
Peer-Reviewed PaperTracked over timeA laboratory mortar study found its best bacterial dose changed with calcium levels; exposure tests showed lower ion uptake, not lasting crack repair.
-
Evidence date ·How conditions can pause and restart bacteria in self-healing concrete
Peer-Reviewed PaperTracked over timeA study tracks the delay from spore germination to enzyme activity and deposition. The available evidence does not establish crack-healing performance.
-
Evidence date ·Pineapple fibres change how bacterial concrete handles load and water
Peer-Reviewed PaperTracked over timeA laboratory study links pineapple fibres to strength gains, but longer fibres increase water uptake. Mineral deposits suggest healing potential, not proven repair.
-
Evidence date ·How adding bacteria changed concrete under load
Peer-Reviewed PaperTracked over timeBacterial concrete mixtures were stronger, developed finer cracks and absorbed less water in lab tests. Long-term self-repair remains unproven.
-
Evidence date ·How bacteria might seal a concrete crack and what that repairs
PreprintTracked over timeBacillus subtilis spores are proposed to deposit minerals in concrete cracks, but this preprint’s healing and strength claims need careful reading.
-
Evidence date ·Bacteria that survive cement chemistry filled narrow mortar cracks
Peer-Reviewed PaperTracked over timeMore than 200 bacterial isolates were screened for enzyme activity and alkaline survival before 0.3 mm mortar cracks were tested for 28 days.

Evidence date ·Can a porous mineral shelter keep concrete repair bacteria ready?
Peer-Reviewed PaperTracked over timeA 2026 laboratory study tests porous perlite as a shelter for repair bacteria, tracking mineral-making after aging, drying and temperature changes.
