Concrete With A Lower CO2 Footprint
Low Emission Concrete In The Works
One of the world’s largest cement companies, CEMEX, and a company that develops nanomaterials, Carbon Upcycling, together will utilize nanotechnology to research the production of low emission concrete. Annually, CEMEX uses 3 million tons of industrial residue as additives to cement and concrete; however, a good portion of waste still ends up in landfills. To improve its carbon footprint, this initiative seeks to double CEMEX’s reuse of industrial residue to 6 million tons, keeping more waste out of landfills.
Typical industrial residue has a low reactivity, cannot be recycled, and ends up in landfills. Carbon Upcycling’s nanotechnology transforms fly ash and slag, so they have higher reactivity properties and cementitious properties. This results in a new additive for cement that allows for the creation of concrete with a lower CO2 footprint. Initial results from the research are expected in mid-2021.
