Corrosion of reinforced concrete is a major concern in the United States infrastructure. It is possible to create corrosion resistant concrete structures through careful evaluation of the environmental and mechanical demands on the structure and by selecting appropriate materials to meet those demands. Designers, owners, contractors, and suppliers can work together to produce a concrete capable of withstanding the harsh demands of today and the future. Specifying a ternary mixture with fly ash and slag will produce a less permeable concrete which will both extend the time to corrosion initiation and decrease the rate of propagation. Furthermore, using reinforcing less susceptible to corrosion will extend the service life of the structure. Epoxy coated rebar provides a protective coating for the steel to prevent corrosion. This research seeks to demonstrate the effectiveness of using a ternary blend in conjunction with epoxy coated rebar in helping to decrease the odds of corrosion by reducing permeability and providing a protective coating for the reinforcing. |
