Resumen de los autores
Abstract Ambient carbonation—the passive uptake of atmospheric carbon dioxide into the alkaline pore solution of concrete—has been proposed to mitigate carbon dioxide emissions from cement production. Herein, we apply thermodynamic and diffusion-based analyses within a Monte Carlo framework to evaluate the extent and rate of ambient carbonation across concrete formulations and geometries (i.e., described by their surface-to-volume ratio, ranging between 0.01-to-80, /m), globally. The analysis indicates that, by 2030, the carbonation of concrete placed in service, globally, under ambient…
