Reducing the Carbon Footprint of Concrete with Carbon Dioxide

Abstract: Concrete is the world's most important and widely used construction material. CarbonCure's technology recycles waste carbon dioxide (CO₂) to make stronger and greener concrete. Once injected into the wet concrete mix, the CO₂ reacts with calcium ions in the cement paste to form a nano-sized calcium carbonate mineral particle that becomes permanently embedded in the concrete. These nano-sized particles improve the compressive strength by 8-12%, enabling the concrete producer to reduce cement content in the concrete by 4-8% without compromising strength, thus reducing the Carbon Footprint of the concrete.

The CarbonCure Technology is being used by over 180 concrete plants in North America which have produced over 5 million cubic yards of Concrete, reducing CO2 emission by 150 million pounds.
