Using bacteria to make self-healing concrete

- Concrete is the most commonly used construction material on earth, found in everything from roads and buildings to bridges and sewers.
Although concrete is strong, it's prone to cracking. To solve this problem, researchers from the University of Bath are investigating how certain species of Bacillus bacteria could be used to make concrete which heals itself.
The Microbiology Society is a membership charity for scientists interested in microbes, their effects and their practical uses. It is one of the largest microbiology societies in Europe with a worldwide membership based in universities, industry, hospitals, research institutes and schools.
Our principal goal is to develop, expand and strengthen the networks available to our members so that they can generate new knowledge about microbes and ensure that it is shared with other communities. The impacts from this will drive us towards a world in which the science of microbiology provides maximum benefit to society.

My sister decades ago tried to repair cracks in our terrace with mineralic cat litter slurry. I don‘t remember the brand, but our cat (german house cat, short hair) abused the excessive litter my sister sprinkled on (my dad assumed due to her lazyness she used dirty litter). So did the neighbors cats. Next spring the smell had gone, and the cracks (no preferred direction) disappeared.
Thank you for this providing this video its an interesting area for a natural miracle that bacteria can effectively work for this healing process.
I hope that this vast culture of bacteria to be used in many concrete applications will not change ecology, or start having adverse effect on coral reefs.
What effect does it have on the mechanical properties?
what medium did you use for the bacteria?
Time lapse please!
I wonder if this will be the solution to the scarcity of construction-grade silica sand. If these bacteria can do this, maybe they can do it in a variety of substrates
Thank you for this great presentation. I intend to undertake research on self-healing concrete using microcapsule agents, I would love to know where I can acquire these microcapsules. I will be grateful for your response.
Sir, how to culture sporosarcina pasteurii bacteria with minimum use of resources at lab??
sir i want these bacteria can this bacteria i creat i want procedure for made of bacteria
Amazing
We have a patent for entrapment of microbes in an open-cell polymeric material that can be tested to last the concrete mixing and forming. All ancient buildings in India used a concrete mix that allowed these bacteria to grow and smoothen the concrete over time
Could you please give me the details of the seller of self-healing cement?
Have you heard of Sporecrete? Does it actually work?
From where could I purchase this bacteria. I need it for my project
where is this now?
It's same method with grate wall china concrete
cracks are fine, but looks like if they escape it can multiply outside the structures too, after all outside the concretes there are all voids, underwater calcium and dissolved CO2, calcium carbonate causing increase in alkalinity . just imagine if the growth of bacteria becomes uncontrollable, there will be concretes everywhere, and if it enters human body, that will be a problem .. if absorbed by plants , I can actually sense this to be a risky innovation . if I am wrong please explain me
How do we get these bacteria for project purpose
And what will the little critters do the the construction workers who breath them in their lungs...!
