Evidence date ·A bacterium and thickener were tested together to repair concrete cracks
Peer-Reviewed PaperTracked over timeA 2023 study paired soil-derived Bacillus cereus with four thickeners, reporting over 90% crack repair and a 30-second initial water-penetration time.

Evidence date ·Predicting crack-area repair in concrete with bacteria and fibers
PreprintTracked over timeA July 2023 study compares models for predicting crack-area repair in concrete with bacteria and fibers. What do its strong fit scores actually tell us?
-
Evidence date ·How bacteria-associated minerals connect repair mortar with cracked travertine
Peer-Reviewed PaperTracked over timeA 2023 study placed bacteria-based mortar in artificially aged travertine, a building stone, then used imaging and nanoindentation to assess mineral growth and contact.

Evidence date ·How old mortar on recycled concrete helps crack-sealing bacteria work
Peer-Reviewed PaperTracked over timeA laboratory study found coarse recycled concrete particles sealed small cracks better than fine ones, but water flow revealed why closure alone can mislead.
-
Evidence date ·How wood ash carries bacteria into self-healing concrete
Peer-Reviewed PaperTracked over timeResearchers compared direct bacterial mixing with wood-ash carriers, then measured concrete strength—separating visible crack closure from structural recovery.
-
Evidence date ·How bacterial mineral deposits formed at small concrete cracks
PreprintTracked over timeA 2022 experiment used bacterial spores and calcium nitrate, then measured crack closure and water-permeability repair after 28 days of wet–dry cycles.
-
Evidence date ·A treated wall reveals a bacterial mix for concrete surface repair
Peer-Reviewed PaperTracked over timeResearchers tracked bacteria on treated indoor concrete walls and tested a mix with improved mineral-forming capacity. Lasting crack sealing remains an open question.
-
Evidence date ·At a Vilnius footbridge, rain meets concrete designed to seal cracks
Peer-Reviewed PaperTracked over timeResearchers cracked bridge beams to test bacteria-assisted concrete: 14–17% laboratory crack-width reduction, plus a rain-exposed field experiment.
-
Evidence date ·What can bacteria help repair inside lightweight concrete after severe heating?
Peer-Reviewed PaperTracked over timeA 500 °C lab test found lower water uptake after 28 days of curing, while strength and stiffness diverged; it was not building-safety proof.

Evidence date ·A computer model separates carrying more from bending less in bacterial concrete
Peer-Reviewed PaperTracked over timeA beam simulation predicts a 20.2% capacity gain for one bacterial mix, while showing why carrying more load and bending less are different outcomes.
