ABSTRACT
The Fiber Reinforced composite rods (FRP rods), presenting a high strength to weight ratio, resistant to repeated loading and not subjected to corrosion. Thanks to these features they are widely used in the construction industry as reinforcement for concrete structures. The composite reinforcement is usually made of glass or basalt fibers and has special outer relief providing a good adhesion to concrete. The carbon fiber has higher characteristics but rarely used because of its high cost.
