Claims15
A method of carbonating concrete materials during mixing of the materials comprising
- (i) placing a predetermined amount of concrete materials in a mixing chamber of a mixer, wherein the concrete materials comprise cement and water, and mixing the materials in the chamber;
- (ii) starting addition of carbon dioxide to the mixing chamber so that carbon dioxide contacts the mixing concrete materials and reacts with the cement to produce carbonated concrete materials, wherein the carbon dioxide comprises solid carbon dioxide and gaseous carbon dioxide;
- (iii) monitoring the amount of carbon dioxide added to the mixing chamber;
- and
- (iv) stopping addition of carbon dioxide into the mixing chamber when a predetermined amount of carbon dioxide has been introduced, wherein the predetermined amount of carbon dioxide is between about 1 and about 27 pounds of carbon dioxide into the mixing chamber for each cubic yard of concrete mix in the mixer.
