"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.

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.

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.

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.

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?

Great looking product. I hope it does not require more sand to make. Sand is becoming a very scarce commodity since what everyone needs is river sand, not desert sand.

We need more people to get on board with this. We need more politicians to take action and endorse these better alternatives for the concrete/cement industry. Governors should charge the concrete/cement industry for emitting co2 into the atmosphere. Maybe that way they will switch to more environmentally friendly alternatives.

Maybe use the CO2 from the truck to make ready mix

So if the concrete blocks drop then the trapper CO2 will be released back into the atmosphere, right?

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.

Isn't it easier to trap and use co2 gas for other industrial reasons like fire extinguishers?

If you have a good plan, the company will be at a deficit for indefinite amount of time, just like any other companies out there. So, might as well cut the price on the cement right now. Also, government should provide green technology credits and subsidies to business who are buying this cement in order to make it an attractive product.

The big elephant in the room is they said during the curing process so basically they’re putting it in an oven to curate. What about when you’re pouring a sidewalk or driveway are you going to hang an oven over it to bake it to make it cure? 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

Because I know the reality of the truth that is really happening, I was understandably sceptical, but trapping carbon inside the cement is really brilliant, not just eliminating the production of the emissions, but Also trapping thermal gases inside the substance, creating insulation. Brilliant, it could not only reduce emissions but create a new hybrid manufacturing system that injects harmful emissions inside of building materials as insulation.
