An accelerated-curing concrete masonry unit mixture includes aggregate material, hydraulic cement and spent blasting abrasive particles, and may also include paint residue particles. A porous component is applied to at least a portion of the limb within the outer cover. The chelating agent can also have a variety of forms, but is preferably in the form of a metal chelate, a salt, an acid, or combinations thereof. The provision of the composite film consisting of the gate oxide film and the groove side wall between gate electrode and the substrate in the groove upper part enables reduction of the parasitic capacitance of the gate electrode. This invention is also directed to pharmaceutical compositions containing the compounds of the invention, and methods of using the compounds to treat disease-,states characterized by thrombotic activity.
