Abstract:
Modified fibers that are texturized fibers coated with resin(s) are disclosed. The invention also discloses structural materials reinforced with the modified fibers including concrete, grout and wallboard products. Concrete products and dry concrete mixes contain cement, resin coated (epoxy, acrylic and so on) coated carbon fibers, and any optional components such as silica fumes, slag, stone, sand, and/or other aggregates. The resin coated carbon fibers have a length of about 1 inch 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 are also disclosed.
