Carbicrete’s technology enables the production of high-quality concrete using mineral waste and CO2 as raw materials.
Using a process called carbonation activation, we eliminate the need for cement in concrete by replacing it in the mix with ground steel slag, a by-product of steel-making. The concrete mix is poured into molds just like conventional concrete and is then cured using CO2.
During curing, the gas becomes a solid, binding together the slag granules, and giving the concrete its strength.
The process can be implemented in any precast concrete manufacturing plant.
Lower your carbon footprint through carbon-negative concrete
Carbicrete’s process avoids the GHG emissions associated with cement production (about 2kg of CO2 per standard-size concrete block) and then injects CO2 (1kg per block) into its products. Because more CO2 is consumed than emitted during the process, it is carbon-negative, allowing users of the technology to lower their carbon footprint.
