Carbicrete

Carbicrete is a Montreal-based cleantech company that develops low-cost building solutions that contribute to the reduction of greenhouse gas emissions. The company has developed a technology that can be implemented or adopted by any standard concrete production plant.

Carbicrete developed a technical process for producing concrete using mineral waste and CO₂ as raw materials. The process by which the concrete is produced is called carbonation activation, where cement is removed from concrete manufacturing by replacing it with steel slag, a by-product of steel-making. The resulting concrete mix is poured into molds, like conventional concrete, but is cured using CO₂. During the curing process, the CO2 becomes a solid, binding to the steel slag granules, which gives the concrete its strength. The process can be implemented at any concrete plant that uses precast concrete methods.
