  • The cement that absorbs carbon dioxide - CEMBUREAU

    The other relationship is a much more beneficial one. Concrete that is exposed to the air naturally undergoes carbonation, a process where carbon dioxide is slowly reabsorbed into concrete’s structure and reacts with the calcium hydroxide found there to form calcium carbonate. This locks CO 2 away, providing a stable long-term storage solution.
