Patent number: 8859105Abstract: A coating for a reinforcing material, such as metal rebar, that increases the adhesion between the reinforcing material and a matrix, such as a cement-based mortar or concrete, in which the reinforcing material is embedded. The coating may comprise a glass frit mixed with a refractory material, such as dry Type I-II portland cement. The coating is bonded, typically by heat, to the surface of the reinforcing material. The reaction of the refractory component, e.g., portland cement, when the reinforcement, e.g., metal re-bar, is embedded in a matrix, e.g., fresh mortar or concrete, prevents the formation of soft precipitates at the interface of the matrix and its reinforcement. One coating comprises portland cement Type I-II combined with a commercial alkali-resistant glass frit. This coating is applied to a steel rebar and fired to bond to the rebar.Type: GrantFiled: July 7, 2011Date of Patent: October 14, 2014Inventors: Donna C. Day, Melvin C. Sykes, Charles A. Weiss, Jr., Philip G. Malone, Earl H. Baugher, Jr.

Publication number: 20110100265Abstract: A “green process” and system employing a first operation of electrophoresis in a liquid suspending selected solids to introduce the suspended solid particles as micro- or nano-particles, or both, into pore spaces of a porous non-conductive medium. A second operation uses electro-transport to move ions of solids into small pore spaces inaccessible via electrophoresis alone to grow solids in these smaller pore spaces to a size that may fill them, thus increasing the density and strength of the medium. The process yields a material that has improved strength, reduced porosity, high density and, in select applications, resistance to formation of mildew, mold, fungus and the like. Certain applications also enable decorative colors and florescence to be introduced to the media. Materials made from the process include high strength concrete construction panels, “backer boards,” work surfaces, counter tops, complex decorative configurations, strong thin walled items, and the like.Type: ApplicationFiled: October 29, 2009Publication date: May 5, 2011Inventors: Philip G.

Publication number: 20100247860Abstract: A method of coarse enameling material, such as the surface of conventional rebar, which increases adhesion between the surface and a matrix, such as a cement-based mortar or concrete, in which the material is embedded. In one embodiment, a glass fit is fired onto a surface to achieve an enamel finish, the finish is then cooled and heat softened. A refractory material, such as dry portland cement, is applied to the heat softened enamel, and the resultant coarse coating is then fired and cooled to produce a final hard coarse enameled surface. The reaction of the refractory component in the coarse enameled surface upon insertion in fresh mortar or concrete prevents the formation of soft precipitates at the interface of the cementitious matrix and the coarse-enameled reinforcement. One embodiment involves adding portland cement Type I-II to a softened glass frit as a final coating over an initial base coating that if fired on the steel to prevent corrosion of the underlying steel.Type: ApplicationFiled: June 4, 2010Publication date: September 30, 2010Inventors: Melvin C.

Patent number: 7763155Abstract: An Electro-Osmotic Pulse (EOP) system is used to dewater structure, both natural and manmade. Preferably, the system employs durable, dimensionally stable anodes affixed to structure in a configuration designed to maximize electrical contact with the structure and minimize electrode gas generation. The anodes and cathodes are attached to a DC power supply that provides a voltage potential between them. DC power is cycled until the structure has been sufficiently treated. Select embodiments employ perforated metal pipes as cathodes for the purpose of transport and drainage of fluids. In select embodiments of the present invention, the cathodes are connected to variable resistors designed to reduce opportunity for corrosion of buried metal objects in the vicinity of the EOP system. Select embodiments employ a pre-specified pulse train of DC voltage pulses to migrate water from under a crawl space while moving available cations in the soil. Select embodiments also protect large structures such as concrete dams.Type: GrantFiled: June 1, 2005Date of Patent: July 27, 2010Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Philip G.

Patent number: 7135102Abstract: A system and method for dewatering particulate materials employs an improved dewatering probe generally including a single non-conducting pipe having a plurality of holes or slots, an anode mounted on the pipe adjacent one end of the pipe, and a cathode mounted on the pipe adjacent the opposite end of the pipe. The pipe serves as both a sonde for mounting the anode and cathode and as a well for extracting water that collects around the outside of the pipe and flows into the interior of the pipe through the holes or slots via gravitational and electro-osmotic forces. A pump may be used to extract both collected water and accumulated electrolytic gases from the pipe's interior. In embodiments, an array of guide electrodes is mounted on the pipe in addition to the anode and the cathode in order to deflect the major current flow out into the body of surrounding particulate materials. The guide electrodes also facilitate rapid depolarization of the probe.Type: GrantFiled: April 24, 2003Date of Patent: November 14, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Sean W.
