ABSTRACT:
Concrete products and dry concrete mixes comprise cement, acrylic coated carbon fibers, and any optional components such as silica fumes, slag, stone, sand, and/or other aggregates. Preferably, the acrylic coated carbon fibers have a length of about 2½ inches to about 6 inches. A method of reinforcing concrete comprises mixing the cement, the acrylic coated carbon fibers, any optional components (such as silica fumes, slag, stone, sand, and/or other aggregates), and water to form a cement slurry, and letting the slurry set to cure the cement and form bonds between the cement and the carbon fibers, thereby obtaining reinforced concrete.
