Abstract
A method for curing cementitious articles includes flowing dry steam and carbon dioxide (CO) simultaneously into a curing chamber containing a cementitious article. A relative humidity within the curing chamber may be between about 50% and about 70% and a temperature within the curing chamber may be between about 50° C. and about 70° C. A dry steam and COmixture with a COconcentration between 2.5 vol % and 40 vol % is provided in the curing chamber and the cementitious article is cured for a duration between about 4 hours and 16 hours. Cementitious products cured with the method may have a COuptake of greater than 15 wt % and a mechanical strength at least 10% greater than a cementitious product cured only in dry steam or CO.
