Abstract:Corrosion of reinforcing steel in concrete has been a constant and expensive maintenance problem which
is exacerbated by Maine’s coastal environment, harsh winters, and the use of chlorides on the roads and
bridges. Carbon fiber products are increasingly being used in many applications to replace steel in
structures. Carbon fiber can be used as reinforcing in concrete slabs. Carbon reinforced polymer (CFRP)
is non-corrosive and can be made into rigid bar and used as reinforcement. It is light in weight, strong,
non-magnetic, and non-corrosive and also has a low thermal linear expansion coefficient. Carbon Fiber
Composite Cable (CFCC) is a cable made with carbon fiber and polymer composite. As a pre-stressing or
post tensioning strand it has relaxation properties very similar to that of steel. This material could prove to
be a very good tool in our battle again corrosion in bridges.
