Concrete is the most abundant substance on Earth after water. But a key ingredient in concrete has always been cement, the production of which accounts for 8% of the world’s CO2 emissions.
CarbiCrete's breakthrough technology, which can be implemented in any concrete plant, makes it possible to produce concrete without using cement.
In our concrete, cement is replaced with steel slag, a by-product of the steel-making process that is often placed into landfills.
Using a process called carbonation activation, CO2 is injected into the wet concrete to give it its strength. As a result, any product made using CarbiCrete technology permanently sequesters CO2, while turning industrial waste (steel slag) into a high-quality construction product.
Concrete made using this process meets the same specifications as cement-based concrete, has lower material costs, possesses better mechanical and durability properties, and reduces efflorescence in products like CMU blocks.
The end result? A cost-effective process for making precast products that reduces concrete makers’ carbon footprint.
Sustainability & ESG Rating
Removing the cement, and implementing CO2 injection, results in a negative carbon concrete
