I found this awesome quote along with Brad’s “Awesome Stories” about people working for the greater good – stories always worth reading!
This week Awesome Stories brings you solutions to create better buildings that protect our precious planet like bio-concrete, eco-friendly hardware, solar smiles and slowing down.
Henk Jonkers, of the Delft University of Technology, in the Netherlands, has come up with a new concrete that heals itself with bacteria. Concrete is a very alkaline, dry, harsh environment. Jonkers choose bacillus bacteria because they thrive in alkaline conditions and produce spores that can survive for decades without food or oxygen. The bacteria and calcium lactate are added to the concrete creating a limestone producing mix embedded within the concrete. The bacteria is dormant until cracks form, allowing water in to activate the bacteria which feed on the calcium to create new limestone that fills the cracks. This could be the future of building technology. Professor Jonkers is also working on creating a mix that can be sprayed onto old, cracked concrete to…
