Carbon curing or mixing in concrete is promising for carbon dioxide sequestration. Here, the authors show that the increased use of binder material to compensate the loss in compressive strength and electricity for carbon dioxide curing is more likely to increase carbon dioxide emissions on a life cycle basis for carbon cured or mixed concrete.
