Durability behavior of fiber reinforced polymer and steel reinforced polymer for infrastructure applications
… exposed to harsh weather. In the last decade, composite reinforcement systems are internally or externally applied to concrete structures instead of traditional steel reinforcing bars, or to strengthen concrete elements in flexure and shear. However, studies regarding the long-term durability …

Manufacture and rehabilitation of guard-rail posts using composites for superior performance
The effectiveness of an external composite reinforcement in improving the strength and durability of a conventional CCA treated wood post was studied. A combination of HMR as primer and epoxy as adhesive was found to provide the best possible adhesion of a glass fibers to CCA treated wood. Wrapped …
