Abstract:
The use of corrosion-resistant reinforcing bars for design lives greater than 50 years has received increased attention over the past 20 years. Interest has been shown in the use of metallic coatings for steel reinforcing bars and new types of solid corrosion-resistant stell. Copper-clad reinforcing was discussed asa corrosion-resistant reinforcing bar system as early as 1967 and again in 1979. To date, no significant structures have been constructed using these materials; however, several long-term laboratory tests have been conducted showing that copper-clad bars may be a viable option for corrosion protection. This paper discusses te performance of copper-clad bars in condrete in relation to black bars.
