Bond critical frp
WebThe bond between FRP system and the existing concrete is critical, and surface preparation is essential to most applications. Any existing deterioration or corrosion of internal reinforcement must be resolved prior to installation of the FRP system. ACI 318-11 Appendix D contains provisions for calculating design strengths … WebJul 1, 2007 · Bond testsFor contact-critical applications there is a requirement for intimate contact but no specific requirement for adhesion of the FRP to the concrete substrate [9]. Nonetheless, on-site pullout tests were conducted to evaluate the FRP-concrete bond two years after the wrapping had been completed.
