Fresh Concrete 1: CarbonCure
|Recorded:||Wednesday 23 March 2022
|Presented by:||Eric Dunford, Senior Director, CarbonCure
This first Fresh concrete event featured joint winners of the 2021 NRG Cosia Carbon XPrize - CarbonCure and CarbonBuilt. Each demonstrated a different way in which concrete can be manufactured using CO2, reducing both the embodied carbon of the concrete and also permanently locking in captured CO2 emissions. Deployment of their technologies, to avoid and reduce carbon emissions, has been described as a gamechanger for global decarbonisation.
Carbonation is the naturally occurring process in which concrete absorbs CO2, permanently removing it from the atmosphere. The rate of carbonation depends on the type of concrete (or cement-containing product), the conditions to which it is exposed, and its design - in reinforced structures carbonation is designed to be limited to protect steel reinforcement. Innovative industrial carbonation technologies are being developed to enhance and accelerate carbonation and consequently remove large quantities of CO2 from the atmosphere.

Already utilised in projects across the US, including the new Amazon HQ, in Washington DC. CarbonCure’s innovative technology injects captured CO2 into concrete during mixing, and uses wastewater in the batching plant to convert CO2 into minerals for use in new concrete mixes.
Fresh Concrete, produced in partnership with The Building Centre, is intended to be a platform for knowledge sharing for all construction professionals, bringing a fresh approach and fresh thinking for concrete.
