Corrosion-Free Carbon Fiber Reinforced Polymer for Prestressed Piles
The Virginia Department of Transportation has released a report that investigates the feasibility of replacing traditional steel strands and spiral reinforcement in bridge piles with carbon fiber reinforced polymer (CFRP) strands. CFRP is a corrosion-free material, whereas the conventional steel reinforcement used in a traditional pile is prone to corrosion when exposed to chlorides. Corrosion-related damage in prestressed elements can occur in both pretensioned and posttensioned strands.
