Evidence date ·How bacteria embedded in concrete are proposed to seal cracks
PreprintTracked over timeBacterial spores and nutrients are built into a proposed concrete mix, with water and oxygen enabling mineral formation to fill cracks. The design remains conceptual.
-
Evidence date ·How crack pathways shape concrete that can seal its own cracks
Peer-Reviewed PaperTracked over timeA 2025 computer simulation traces how crack geometry, water and mineral formation shape bacterial concrete healing—and when deposits block transport.
-
Evidence date ·Could bacteria give recycled tire rubber a useful role in stronger concrete?
Peer-Reviewed PaperTracked over timeA lab study found that one bacterial mix nearly matched conventional concrete’s crushing strength; separate water-cured samples showed visible crack closure.
-
Evidence date ·Bacteria may close concrete cracks, but strength still matters
PreprintTracked over timeControlled tests found crack closure within 21 days and stronger manufactured-sand mixes, but the findings do not yet show durable structural repair.
-
Evidence date ·When the material sheltering bacteria shapes concrete repair
Review or Meta-AnalysisTracked over timeA review explains how bacteria seal concrete cracks with calcium carbonate and why protective carriers, permeability and steel corrosion matter.
-
Evidence date ·When water helps bacterial concrete repair and when it acts too soon
Peer-Reviewed PaperTracked over timeFreeze-thaw tests tracked recoverable bacteria, while water curing cut counts and simulated rain produced only 13.6–16.8% crack closure.
-
Evidence date ·How the material carrying repair bacteria changes concrete under load
Peer-Reviewed PaperTracked over timeA laboratory comparison tests three carriers for bacterial concrete, revealing different results under compression, bending and environmental exposure.
-
Evidence date ·How bacteria and mix ingredients shape concrete predictions
Peer-Reviewed PaperTracked over timeA 2024 study models concrete strength and workability from bacteria and mix ingredients, then compares prediction scores without proving actual crack repair.
-
Evidence date ·How bacterial repair changed damaged concrete’s grip on steel
Peer-Reviewed PaperTracked over timeA lab study treated damaged lightweight concrete in three ways, then retested its grip on steel. The 17.9% gain and weaker compression recovery need context.

Evidence date ·What bacterial capsules achieved inside cracked mortar
Peer-Reviewed PaperTracked over timeA laboratory study compared three bacterial species in capsule-filled mortar, showing narrow cracks can fill in water while durable repair remains untested.
