- 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.
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
Why don’t you do something about it? Hope you realize the harm you are doing by not making this an open patent. Your greed does more harm than good
Time lapse please!
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.
Yet a lot many aspects are to be explored.
It's a common bacteria found in the soil
@uma chauhan you will have to procure them from culture collections. You can also isolate them and screen them for Calcite preparation
@uma chauhan There are bacterial cultures mentioned in the literature. You can use the reported cultures. Check the websites of culture collections in India first. International culture collections will definitely have the reported cultures.
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.
bro same
Thank you for this providing this video its an interesting area for a natural miracle that bacteria can effectively work for this healing process.
VERY-INTERESTING :)
THANK YOU FOR SHARING :)
THANK YOU FROM ISRAEL :)
You are very welcome :)
From where could I purchase this bacteria. I need it for my project
Carolina Biological has Bacillus Pseudofirmus cost around 40 USD if I can recall
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
First of all the bacteria is encapsulated so it wont happen and also there is range of akalanity in which it can survive so better encapuslation better resluts less harm chances
These are environmental microbes. Since there is currently not forming concretes everywhere, or killing people, I'm not convinced that is a significant worry
What effect does it have on the mechanical properties?
where is this now?
I'm a civil engineering and I'm so interested in doing this project but I don't know where I can get these bacterias...or how I can produce them since I'm not a biotechnologist I don't find sites where this is explained...pls If someone could give me some information
Where to buy this Bacteria? Need for my major project
Hii bro did you complete your project on self Healing concrete
Could you please give me the details of the seller of self-healing cement?
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
what medium did you use for the bacteria?
How do we get these bacteria for project purpose
Where to buy this Bacteria? Need for my major project
And what will the little critters do the the construction workers who breath them in their lungs...!
Odd how the romans didn't need to add bacteria to their concrete that's still strong a thousand years on...
I am a civil engineer student in Delhi. I am making this as a project. I want those bacterias. In India these bacterias are not available. Kindly help me. I hope for a positive reply from your side.

Nishok txt me on watsap or kol me on 8744020203
I can help u i am also working on the same project
Hello Nishok Kumar. I am Dr Trupti Sharma. Not all but at least one of the cultures possibly could be available in India. Try writing to culture collections or going through their online catalogues.
Thannks sir salahuddin ghazi
Trupti Sharma. I wrote to different collection centre. But i didn't get any positive response. If you know some centres then kindly give me the details.
Nishok Kumar Try international culture collections. Like DSMZ Germany. It will cost you but you they have it. I had procured them for DSMZ for my research.
i am studying btech and i was interested to do the project of self healing concrete after seeing this video i was much interested to know what is the bacteria used in self healing concrete and how it is available in the nature and in what form we should use the bacteria can you please give the reply
Bro have u done this project, plzz rply i also have to do project for my btech if you can help.
@@pawanB2000 no bro I have taken anathor topic for my project
@@saipavankumar7221 good idea bro thanks might take this topic for phd lol...
I have a crack on the side of my house. Can I go to the local hardware store and purchase this as a filler material? This could be a huge cost savings
Brian Lockwood It hasn't yet hit the market. These are lab studies under optimum conditions.
Brian Lockwood The whole purpose of this research was/is to develop a cost effective sustainable alternative. You got it right :)
Do you have a guess on when it will hit the market? it will help me decide how long I'm willing to wiat
@@truptijamalpure6308 im personaly doing research on self healing concrete using bacillus subtilis and calcium lactate but since i made concrete sample i havent seen any traces of healing in concrete ?
@@saqibkhan1921 hii sir i am doing a project on this self healing concrete would you help me
Use this bacteria with a liquid solution on critical concrete made from mycelium. The mycelium could replace the steel, and the the bacteria would fill in the porous mycelium and strengthen it further. I was have done a few attempts at using a flash graphene added to the mycelium just before dehydration, attempting to cause it to make a graphene nano thread core, anyway I have had a few interesting results, not trying to sell an idea just throwing info out
an u please advise some good topic in Pavement material for Project ...im in pursuing my master in Transportation Engineering and rightnow im in 2nd year
Sir, how to culture sporosarcina pasteurii bacteria with minimum use of resources at lab??
Have you heard of Sporecrete? Does it actually work?
Hello, currently I'm working on my project for bacteria concrete. Do you know how to check that the bacteria is alive inside the concrete?
can u please advise some good topic in Pavement material for Project ...im in pursuing my master in Transportation Engineering and rightnow im in 2nd year
Where to buy this Bacteria? Need for my major project
Amazing
Where can i buy the material?
Where to buy this Bacteria? Need for my major project
It's same method with grate wall china concrete
sir i want these bacteria can this bacteria i creat i want procedure for made of bacteria
Very interesting . Have any one. Use this bacteria. On the human cell.😮 Or may be just too different to interact.
Which bacteria did u use to heal the concrete can u name the bacteria name
" Bacillus family" Bacteria
Bacillus Subtilis
Bacillus Halodurans etc..
Hii sir or madam iam a civil engineering student i want to do project on this but can anyone explain me about this Bacteria .Because i didn't understand about cultures that what are you discussing . Please can anyone explain me briefly about the bacteria and its availability
Get a book which discusses bacteria
Love from Kashmir
Use Poo
where i can buy bacteria bro
Where to buy this Bacteria? Need for my major project
emerge #penetron
can i use bacillus subtilis for self healing concrete instead of other bacillus culture ? please any one help me
Can this be used to stabilize very sandy roads and trails in central Florida? like this: photos.app.goo.gl/K9bGmaoRMaqE2VZJ6 Where do you get this?
Piss on sand
leave it in a jar
turns to stone
