| Abstract: |
Corrosion of steel reinforcing bar (rebar) is the most significant cause of concrete failure, resulting in expensive repairs, reduced load carrying capacity and premature replacement of concrete structures. This paper will discuss continuous galvanized rebar now available for concrete structures. The properties of this zinc coated rebar and its contribution to improvement of concrete performance will be presented together with the status of related national and international standards and applications in China. The Continuous Galvanized Rebar (CGR) coating process improves product consistency, increases through put and reduces costs. The zinc coating is durable and resistant to abrasion that is routine during transport and construction but is also highly ductile and can be formed after galvanizing to further reduce cost and speeding construction schedules. Once in the concrete, the zinc coating protects the rebar both as a barrier coating and with the well- known sacrificial properties of a galvanized coating. |
