Whole Life Cycle Carbon Uptake Tool
Carbonation is a natural process of carbon uptake in concrete that has been estimated to offset up to 43% of calcination emissions that occur during cement production. But to integrate carbonation into carbon accounting practices, it’s essential to estimate it at a more granular level.
CSHub researcher Hessam AzariJafari has developed a state-of-the-art, material- and facility-specific calculator for carbon uptake in concrete that includes carbonation from the end-of-life stockpiling of recycled concrete aggregates (RCA). This tool can include the details of use-phase uptake and corresponding mix design components when estimating the end-of-life uptake. The calculator estimates carbon uptake through a variety of accessible inputs—including concrete mixture, location and exposure characteristics, and stockpiling conditions.
