Isn't this slavery? :O

wwooooowwwww



[JMichaelParty]

With the presence of water, wont the calcium carbonate dissolve resulting in the presence of carbonic acid which would speed up the corrosion process?

[Zekee27]

yeah no repairs, ok, even though I have my doubts, but how much to build in the first place??? and how long till it really pays off..

[lukchhh]

Audiofreq sent me here :))

[UmbraTractus]

I like the way he says Concrete.

[Severosrighthook]

i dont want this shat. repairing concrete ma azz next this we know those bacteria will develope into killing machine wiping the entire human race. we already have are hands full with skynet already namsayin? we don need this shat namean?

[ShredWithMe1]

@Severosrighthook Are you retarded?

[ShredWithMe1]

@Severosrighthook Like im being serious, im worried.

[andreeaweed]

amazing video

Bacteria everywhere!

[Xello998]

@hyfyv Bacteria is already everywhere including inside your ass and stomach helping you to metabolize food. I wouldn't worry.

[infernoacid]

I am Dutch and I endorse this accent.

[almcken]

1 person does concrete patch work.

[c0N3x]

yea thanks for nothing.. people need jobs.. you just made sure that even more poeple loss there job.. th

[whycuds]

Great work! We need more inventors like this guy.

[snikkel111]

Very articalute pronunciation for a Dutch man!

[katheryncruz24]

Informative. Nice.

[shimlaDnB]

hou - je - kanker bek

[CYNinjutsu]

its a bacteria called Basillus pasteruii and when the concrete crack the bacterial its follow the air through the concrete and its crystallize. BUT no for big cracks as that ..

[dogtired75]

this is pretty IN YOUR FACE!

[TheCivilEngineer22]

I read about this in my civil engineer classes.. very great! :)

[iRaiNg]

@TheCivilEngineer22

Can u send me this information if u have it, because i do not found to much on the web

[Drizzt1343]

This dude sounds like a robot.

[trebing760]

fucking bozos with the comments don't think anything through

[jigglyfidda125]

*masturbates furiously*

[JESULAAA]

@jigglyfidda125 LMAO this comment is so out of place

[OmegaDude22]

Very very nice idea. But what happens when the bacteria run out of food?

[analogWeapon]

Is the bacteria filling the crack strengthening the concrete? I would imagine living bacteria is not as strong as dried concrete, so I don't see how bacteria filling the crack is "fixing" anything. Is there a website with more information?

[yazuak]

He said it fills it with calcium carbonate, not the actual bacteria.

[xerfes]

@yazuak The concrete is pumped with bacteria that produces calcium carbonate if exposed to air and water.

[ingarrecibo]

@analogWeapon Hi! It is not the bacteria filling the crack... it is a side product of its activity there after contact with O2. Look at Delft website.

[rgj798]

Okay so it doesn't help the environment, The expense of introducing the food into the concrete probably matches the cost of maintenance and what happens after the bacteria runs out of food?

[rgj798]

as a civil engineer in training this turns me on

[apopheniacMCMLXXXIX]

That's really clever.

[prolefeedprocessor]

Hot people changing the world. Awesome.

ik versta er geen zak van. welke taal is dat?

[glennvanderakt]

dat meen je niet...

[Corivatt]

love his accent

[isk8anddrum]

this guy looks like house

[TIMSY47]

This guy looks like ME! Sent from Holland to me from a firend who spotted the likeness. My wife agrees.

[dannyweeks12345]

things like this i would love to see in normal day life, its great but I people dont like or push for change. I think this alot about brilliant new technology and inventions

[gman17rapper]

This product will never be published, they will destroy it. Because some people.. politicians and construction companies make huge amounts of money... of public money by fixing each time the cracks.

[ouiser5000]

No, the money saved on repairing concrete will be spent building more. That's the way it's always been. Was the Haber Process suppressed because it meant less land was needed for the same amount of food? Of course not! We use the same amount of land for more food, and we'll use the extra concrete to build higher buildings.

[andrew1zy]

I wonder who has the patent

[yoshinibble123]

Innovative...

[ethicsg]

Could this be combined with geo-polymer concrete? If it is repaired with calcium carbonate would it be better to start with a limestone base?

[maceng08]

Really interesting, great concept
