CFRP is a corrosion-free option for pre-tensioning and post-tensioning applications on concrete elements.
CFRP is a corrosion-free option for pre-tensioning and post-tensioning applications on concrete elements. It performs comparably to steel in the finished product in terms of material handling, structural erection, constructability, and other factors.
CFRP’s benefits compound with its promise of lower life cycle costs, including reduced maintenance and rehabilitation work. This translates to increased worker and motorist safety. It also means that cost savings stay in the roadway user’s pocket in the form of less delay (and fuel consumption) plus reduced vehicle wear and tear.
Agencies from Maine to California are recognizing a host of practical advantages of
CFRP, which include eliminating the need for grouting in post-tensioning applications, more tendon replacement options, and more options for repairs from high load hits. Plus, the cost of CFRP, which, like steel, is only a fraction of the cost of an overall bridge project, is falling as applications, supply, and technology advance.
FHWA has found that it is in the public interest, for a five-year trial period, for Virginia DOT (VDOT) to specify CFCC in prestressed concrete piles in areas deemed highly-corrosive. Helpful technical guidance is available here:
