Every year, the production of cement accounts for 8 percent of global CO2 emissions. If the cement industry were a country, it would be the world's third-largest emitter of CO2. One company working to reduce the carbon footprint of cement is New-Jersey based start-up, Solidia Technologies. Its cement mixture and curing process can cut CO2 emissions by up to 70 percent.

I like this guy. "We have to use 3rd party testers as no one's going to believe our data" Those are the confident words of someone throwing down the gauntlet and saying come at me, I can back it all up. He's also realistic about implementation which is a nice change from all the CEO's who are just talking 100year future BS. Unfortunately they are still a private company. But I'd be keeping an eye on them. If what they say is correct that it's actually cheaper, stronger, less water, better colours than the second it gets approved and can be made in ready mix companies will switch in a second and won't even give a dam about the green side. If you can save the environment and increase profits by doing so, then that's how change will come about.

Soviets done it in the 70s. By putting aluminum slag into the concrete, it releases FAR less CO2 while drying/curing. It's so funny how all these "NEW" ideas are rehashed from old and everyone gets thrilled.

Civil Engineers should know this. There is an "Photocatalytic Cement " which is also known as "Pollution Eating Cement"

@Advanced_Materials_Publishing 8 месяцев назад

yeah, but it is not working like very good. It is a certain type of titanium dioxide which has those propertys. The problem in the construction sector is that it is already very expensive to build if you then add costs to it, people wont accept it. Plus making TiO2 consumes a lot of energy and it is not really "eating" pollutents away. They are still there but in another form. Also it is only acting on the surface but 80 % of the photo active substances do not even have tha chance to act and react. One of the few materials who could change the industry is geopolymers, which why i dedicated my work to them.

@zakiducky 4 года назад

I could see this being a good replacement for existing CMU products on the market, depending on the structural properties, sizes & shapes, and finishes available. If the available Solidia masonry sizes are identical to standard sizes, and prices come in the same ballpark, using them is as simple as writing a small specification or note on a CD set. I’ll have to look these guys up for my next project.

@dess3597 4 года назад

That's what their imply, It's incredibly difficult to "capture" natural CO2 to the point that is easier just to mine the stuff out of the ground or burn something. Capturing burn gas off their kiln would be the cheapest source of CO2 for them.

@Techtachular 4 года назад

Great thought, however I would say probably not. It sounds like the CO2 jumpstarts the curing process. One would not want the cement in the concrete to cure until it’s been placed in the desired location. Typical concrete, made with Portland cement, needs to be placed within 90 minutes of batching to be considered to be within the compliance range (that 90 minutes can be extended with chemical additives). So if their substituting CO2 for water then one must assume that the CO2 should be added to the cement after it’s been mixed with the sand and aggregate.

@garretthinshaw431 4 года назад

I like the idea, because it can be refined and harnessed to inject into other building materials.

@watch50er 3 года назад

@@Techtachular - this version seems to be more of a first generation iteration that focuses on pre made concrete blocks instead of pourable concrete. Not a full solution yet (if ever) but a great means to start to curb the CO2 emissions. If it is viable at all to mix the cement, co2, gravel, and sand on site int a pourable concoction we are not there yet if ever. None the less, since the process is still reliant on Kilns, and pre made blocks are not going away, there is still an avenue to use CO2 smoke capture during the heating phase. All efforts in the right direction.

NEUTERLibs the amounts of increased CO2 in the atmosphere have no impact on plant growth. So reducing it back down to pre industrial levels would not decrease any growth. When plants are grown indoor environments the level of CO2 is increased to 1200-1500 ppm. We are talking about one quarter of that currently in the air.

@user-pf2hv8qw1s 4 года назад

That is what I always say about infomercials, “If it’s so great why isn’t it sold in a store?” We already have NHL which cures in the presence of CO2 and water. It is halfway between cement and non-hydraulic lime. It takes less heat to produce and absorbs CO2 as it cures but takes longer to initially become hard and ultimately does not have quite the same strength (although pretty close.) So for some things you just beef up the thickness. So now I am wondering, chemically, how does this differ?

@GrantSR 4 года назад

They really need to explain how the heck the product is flowed into molds and forms without water. And then how CO2 is "mixed" in with the product. Is the product sifted in dry, and then the mold is suffused with CO2 gas, replacing all the air? Is liquid CO2 used? What!?

I suppose it is some kind of Roman cement (which would be great :) Arguably, the binder could also be seen as a geopolymer as sometimes it is hard to decide which word fits the best and quite some times many different do. Roman cement, or metakaolin-Ca(OH)2-geopolymers, can be made by oneself. But of course it is a good idea to buy a tested product if you want to build with it. The diy way is rather for experimenting but in theory it can be good to make buildings from it.

As of right now if you go to Home Depot and buy a bag of Portland cement 94 pounds and mix it up into Cement properly with aggregate if it’s below 50° outside the It will not cure properly and that’s because they’re adding up to 15% Lime stone
