-
Steel-reinforced concrete structures are used worldwide for a wide variety of civilian and military infrastructural needs. Recently, researchers with the Army Corp of Engineers developed a means to increase the bond-strength between steel reinforcing elements and the concrete matrix. A composite enamel, consisting of a glass matrix embedded with reactive ceramic particles, is applied to the steel before it is embedded in the concrete. The glass provides a strong bond to the steel and the reactive ceramic particles form a strong bond to the concrete. Mechanical tests done by the Corps and at Missouri S&T show that after the concrete sets, the bond strength of the enameled steel is 2-3 times greater than that of enamel-free steel. The glass used in the initial tests was a standard composition used for commercial enamel applications. This invention disclosure describes new glass compositions developed specifically for coating steep elements for reinforcing concrete structures. Specifically compatible with typical steep alloys used to reinforce concrete, and to posses thermal properties (coefficient of thermal expansion and softening temperature) compatible with typical steel alloys used to reinforce concrete, and to possess enhanced resistance to the corrosive, alkaline environment associated with cements.
