There are many silver bullets being created to combat climate change, I have followed this one for a while now and it is certainly one of the strongest we have ready to use today. I hope changes to legislation facilitate uptake.
@@renaissancestatesman because it costs more and it requires modifying longstamding processes which industry is always reticent to do. Moreover, current legislation can hinder its adoption by being too narrowly specific about existing standards for concrete, to the extent that it disallows the use of low carbon concrete.
@@Weaseltube not surprised there are regulatory issues. My issue would be legislation mandating anything. Guess I wasn't clear on that. All for reducing legislation. Construction as an industry is ridiculously slow to change. It doesn't seem there is overly much needed in terms of actual manufacturing changes. Hope they pull it together sooner than later.
@@PsicoPato- a vast number of industries and products do not require government intervention to succeed. In fact those industries with the least intervention do best in terms of innovation.
I would love to see a stress test for this concrete to see how it holds up against traditional structural concrete. As a future engineer currently engineering having information about materials that are both better for the environment but still fulfil their requirements for usage is absolutely amazing for future projects around the world.
Everything he says indicates this should start dominating the market. Even at a 30% cost premium it should be more economical. Wonder what the cost premium actually is though.
I don’t think the cost premium is that high but there are industry practices and regulatory obstacles also that make it harder to change to. I’ve read that they suggest we all contact our legislators to move regulators to change building code so concrete standards are performance-based rather than ingredient-based.
Use of waste CO2, this is epic! I did an short exercise on this in communication studies. This was never anything I could have thought of. Some people in the twilight years of middle of their lives don't care about stuff pertaining to making the planet last longer, this is amazing to see a team coming up with something to help
My God that was brilliant! Simply mind-blown! I hope this change reverberates faster so that we can move towards a carbon negative world faster. I hope we can bring this to India.
Dear Team, not sure how We found this way to Your Channel. Dear Team. Today is my father's birthday. He was a profound "road-maker". He would agree and share great knowledge and Thank You for You and Your teams' brave and true sharings. Very Well presented, indeed.....
Since my passion and design of choice (but not in my budget) is a Monolithic Dome (look it up) which uses concrete applied by spray (as in "shot-crete") I have a deep interest in this subject. My alternative fantasy home is concrete built using cast bricks and a lot of rebar. Wonderful soundproofing and insulative qualities and I cannot speak highly enough of concrete houses. Except for wireless reception. Phone and wireless reception sucks... But the carbon footprint has always been an issue. Still is, since the CO2 impact on the climate may have been exaggerated by the fear mongering scientists (look at solar influence) and it seems that if we sink TOO much carbon the trees will starve... So. Thank you for this inspiration. The only real question is how much more this product will cost over the traditional variety. You didn't mention that.
A curing time of 24 hours can definitely make it worthwhile to the industry, even if it costs quite a bit more. Then, as more people use it, the demand drives up supply, and it should become cheaper very quickly. Concrete curing time can be a big problem for the construction industry, speaking as a designer who works with contractors.
This process plus Graphene is a game changer. New construction materials that are lighter, stronger and greener than existing cement based products. In time they will be cost effective as well.
even better is the effect on Insulation from graphene etc , Homes insulated to a higher standard will require 70 % - 100 % less energy for heating and cooling.
Production cost is all I want to know. Only missing variable. Would be great to see the cost breakdown showing money saved on water vs increased costs elsewhere.
To my knowledge the only Problem is the extremely slow acceptance rate of the building industry (even changing to something cheaper can cost short-term, like adapting to much better drying times changes the process) As he said there are many different types of solutions implemented. But for as long nobody has implemented them on a large scale the building companies (responsible for failures) share the insecure feeling your comment implies. And this is pure speculation: the cement buisness is a giant wealthy industry, those aren't easily outcompeted by newcomers due to their ridiculous advantage in form of captial and don't like to take risks or the above mentioned changes to the process as well.
Thats super cool! But what's the actual durability? How long does it last? How can you scale up production? There is a lot that needs to be done and figured out before we can put it in buildings and bridges. I like that they said it will take a long time for the industry to adapt instead of the idealist ignoring the reality. I hope this works!
This is why innovation is the answer and not regulation. Don't get me wrong some regulation definitely is needed. Technology and innovation will save the planet. Kuddos to this guy and his team doing this.
If this works, this is amazing and absolutely so timely. Currently the construction industry accounts for roughly a 3rd of all greenhouse gas emissions. Reducing that to 0 is necessary in order to achieve draw down.
At this point, I don't think there are any solutions to climate change that won't cost some extra money. If climate change were profitable to prevent, the market might have found a solution by now.
Awesome! I would love to read more literature on this! Also I can't help but wonder, if this technology where to go mainstream, whether or not it could be a incentive for other carbon capture techs to be developed, in order to feed the CO2 that this concrete needs?
Just asking, forgive my ignorance, was it your objective to reduce the carbon footprint? Is that how you came 'to be' ? Thank you for your work and response. Good fortune in 2021.
better understanding of the universe around us will certainly help us solve problems in ways not yet known today . this is the promise of the future . This will be true for global warming ( carbon reduction through concrete renovation is such an example) ... It gives me hope for the future .
can't get CO2 from the atmosphere just like that (concentrating CO2 needs energy). but like Bio Fuel Systems you can use it to neutralize other pollution from industrial plants (or power plants).
Why do you have such a big problem with people talking about things you just happen to not be into? Seems there is some _reason_ you are so hugely invested in negating their efforts, because people who simply don't like things, just do something else. I'm not into golf, but you'll never see me giving anyone a hard time for talking about it. lols
I would agree, but the green nonsense and fear mongering about the climate change is also very evil because it is anti-human and straight from criminal elite globalists.
Hemp mortar soaks CO2 for its life, Roman walls 2000yrs exist. Hempcrete has some cement to work for foundations, it's a natural insulator, ~R4.6/inch vs concrete, transpires moisture & fungi can't grow on it. For N.America, Canada has machines & supplies by the container. Cheers 🍺
What is the name of the company the presenter refers as "we"? where I can read about technology, any real life examples, even as an experiment? Usually there are links below the video with information regarding the subject, but not here. I wonder why.
well it "doesn't". CO2 is not an element. it is broken apart as he mentioned 2:30 and used as C and O2. i guess it exists as carbon in the bricks. would be interesting to see the exact chemical reaction.
This sounds so amazing, part of me is dreading the "but...." that follows. The only "but" is a tenacious industry? Stubborn politicians? This doesn't even require an economic investment if at all, same equipment, same materials. This seems to have no downsides at all, adopt NAO plz!
Whats the extra energy cost and carbon footprint of this technology? Or you are just creating "solution" that doesn't impact anything and just is more expensive?
What about the raw material? Did I miss something ? The concrete industry also consumes a lot a sand. All the supply chain unfortunately has to be taken into account.. it is great anyway !!
Sand is not running out. The type of sand that is needed comes from rivers and there is a lot of it but since they use up the sand that is near the plants, it is not sustainable to haul from further away. Same thing is happening with oil. There is a lot left but the easily extractable one is running out and it costs much more than it’s worth to exploit it. Fracking is one of the new sustainable “solutions”.
2:00 - We "came up with a new cement chemistry"... Tell us! Is it a Patented method or methods (for producing cement and for curing concrete)? 2:20 - You "get CO₂ by capturing waste gas from other industrial facilities, like ammonia or ethanol plants". The CO₂ produced by the cement industry, when burning limestone with the other raw material (in lower temperatures, as you say), can't be used? Or even the atmospheric CO₂ can't be of any use?
So what's the big innovation behind using limestone, aka the oldest cement known to men? Messing up the chemistry with more Co2 than necessary for curing isn't going to make it any stronger, not to speak of the fact that limestone dissolves pretty easily. As much as I hope that they actually invented something useful, it does make my bullshit sense tingle Edit: can't find any scientific papers in his or his companies name. If he had anything to show, he would've made sure the world got to see it. Seems like a lot of hot air
