細菌自癒混凝土

Basilisk Self‑Healing Concrete uses limestone‑producing bacteria embedded within concrete or supplied via additives to form an autonomous repair system that fills cracks with calcium carbonate when water and oxygen enter the damage zone. The bacteria remain dormant until triggered by moisture and oxygen, at which point they metabolize supplied nutrients and precipitate limestone that seals cracks and restores water tightness; the process can repeat multiple times as new cracks form, reducing the need for manual maintenance and targeted repairs.

The technology is offered in multiple product formats suitable for new and existing concrete, with the bacterial system relying on the alkaline environment provided by the concrete or the product formulation to support bacterial activity and growth. Intended benefits include improved durability, reduced ingress of corrosive agents to reinforcement, extended service life of infrastructure and water‑retaining structures, and lower maintenance interventions, while product selection and integration depend on the application and desired repair performance.
