Get more details here on the mobile carbonation chamber that was developed by ORBIX.
Unlike traditional cement that reacts with water, Orbix’s carbonatable binder hardens through reaction with CO2. Under the right conditions, the blocks made with this binder become incredibly strong, reaching about 30 MPa of compressive strength in just 24 hours. But to get those results, the curing process needs to happen in a perfectly enclosed and finely controlled chamber.
That’s why Orbix, the pioneer in slag-based building materials, developed a mobile carbonation chamber. This airtight unit keeps CO2 safely contained, making sure it’s only used by the blocks and doesn’t escape into the environment. However, the high CO2 levels inside make the air acidic, which slowly wears down the metal parts of the chamber. After being used on several projects, it was time for a full overhaul.
And we’ve got good news: after months of hard work, the chamber is now 90% ready! We expect it to be fully up and running by the end of August, just in time to carbonate the 3D-printed blocks at Ghent University. Want to get further updates?
