Self -voltage concrete - a revolution in infrastructure.
What is self -legal concrete?
The innovative material contains bacteria Bacillus pseudofirmus, which in response with water and carbon dioxide produce calcite, Filling microcracks.
Application:
- Bridges: W Holandii zastosowano go na autostradzie A58 – redukcja kosztów napraw o 70%.
- Underwater tunnels: Eliminacja ryzyka korozji zbrojenia.
- Nuclear power plants: Bezpieczeństwo konstrukcji w ekstremalnych warunkach.
Research and statistics:
- Resilience: After 6 months of concrete regenerates to 90% your original strength (Studia Tu Delft).
- Cost: 20% more expensive than ordinary concrete, but the savings on the repairs reach 200%.
An example from Poland:
W 2023 year tests began on the viaduct in Katowice. If they succeed, The technology will go to building standards.
Perspectives:
Researchers are working on a concrete version with epoxy resin microcapsules, which repairs up to 5 cm cracks.
