Reasons cracks are bad!
- Allow water to reach and corrode steel reinforcements
- Weaken concrete structures
- Difficult to repair
Work in this area has already been started: [http://www.youtube.com/watch?v=PyBR3PDPa-c Bio-concrete]
This project is different to ours in that it cannot repair existing structures and Bacillus subtilis cells only remain viable in the bio-concrete for a short period of time. This is not concern for our project as we do not want the cells to survive for a long period of time; just enough time to fix the cracks.
How our project is helpful
- Reduces corrosion rate of the steel reinforcements
- Reduces the need to demolish and re-build concrete structures
- Reduces cement production
How our project is novel
- Filamentous cells- like steel fibers
- Getting the Bacteria to produce the gel/glue that holds it all together.
- Environmental kill switch
- We are working with a well known strain Bacillus subtilis 168 (previous work required specific stains)
