Introduction
The Problem
Fiber Reinforced Polymer (FRP) systems are widely used to reinforce and strengthen concrete structures. However, the concrete surface’s tensile yield strength, is the weakest link in the FRP-concrete bond. This limitation can reduce the overall effectiveness of the FRP system and increase the risk of cohesive failure in the concrete substrate during high-stress conditions.
Moreover, untreated concrete surfaces remain vulnerable to corrosion of embedded steel reinforcement, which can compromise the long-term durability of the FRP solution.
The FRP++ system, incorporating SurCoPrimer as a preparatory step, provides a superior solution by strengthening the substrate, inhibiting corrosion, and ensuring the FRP system achieves its full potential for long-term performance and durability.
Benefits of FRP++
By integrating SurCoPrimer into the FRP application process, the FRP++ system provides unmatched advantages:
1) Improved Tensile Strength:
SurCoPrimer increases the concrete surface tensile yield strength by an average of 200 PSI, creating a stronger foundation for FRP bonding.
2) Corrosion Inhibition:
SurCoPrimer reacts with free calcium and other components in the concrete matrix, forming a protective layer around embedded rebar.
This protective barrier inhibits the electrochemical processes that cause chloride-induced corrosion, extending the service life of both the concrete and the FRP system.
3) Increased Bond Integrity:
SurCoPrimer penetrates deeply into the concrete, creating a denser and stronger matrix that improves the adhesive bond between the FRP and the concrete substrate.
4) Reduced Porosity:
By reducing concrete porosity, SurCoPrimer minimizes moisture ingress, mitigating future deterioration caused by environmental exposure.
5) Enhanced Durability:
The combined effects of strengthening, corrosion inhibition, and improved bond integrity ensure the FRP system lasts longer, performs better, and provides a cost-effective, long-term reinforcement solution.
