CarbonCure retrofits concrete plants with a technology that recycles waste carbon dioxide to make affordable, greener concrete products. Carbon dioxide is now more than just a greenhouse gas—it is a valuable material to help make better concrete.
CarbonCure’s technology is an affordable retrofit to existing concrete plants that allows producers to recycle waste carbon dioxide (CO2) during production to make more environmentally friendly concrete. Carbon dioxide is a commodity supplied by local industrial gas suppliers and stored onsite within pressurized vessels that match the plant production requirements. Once injected into the mixer, the CO2 is permanently converted into a very fine solid mineral blended within the concrete. The technology is designed to work with all production equipment and materials, similar to chemical admixture systems. Engineers make the installation easy by minimizing any production disruptions and overseeing the entire process from initial site visit to commissioning.
The primary reaction involved in CarbonCure’s technology involves carbon dioxide and cement. When CO2 is added to the concrete during mixing, the CO2 reacts with water to form carbonate ions. The carbonate then quickly reacts with calcium ions released from the cement to rapidly form a limestone-like material. This mineral is created in the form of nanomaterials dispersed throughout the concrete mix. The conversion of carbon dioxide into solid carbonate minerals means that the carbon dioxide has become permanently bound within the concrete and will not be released back into the atmosphere. The resulting concrete has a lower carbon footprint.
Nanomaterials—in the form of extremely fine particles—are known to enhance the material properties of concrete but their use has been limited by production, process integration, and cost barriers. The CarbonCure technology enables existing plants to use CO2 to produce and benefit from well-dispersed nanomaterials in concrete, in a practical and affordable way.
