Carbon Cure concrete blocks

I saw this product featured on the evening news. The process introduces CO2 back into the concrete mixture and traps it. The concrete can then be used to make concrete blocks (it is also being planned for poured concrete). Has anyone used this material?

Scott, that's very interesting. All concrete absorbs some amount of CO2 over time, but it's usually limited to the outer layer. The chemistry makes sense, at least with my limited understanding, as the CO2 reacts with the concrete to form limestone--the primary raw material in Portland cement. I have not used it but will look into it on future projects. I'm curious about the process for capturing and transporting CO2 but that's another topic. Thanks for sharing.
Scott,
CarbonCure concrete (and CarbonCure CMUs) have been covered in three GBA articles, the most recent of which was published today. Here are the links:
