Recycling glass fiber, 'F-fiber,' was obtained by the separation of the roving layer from waste FRP and the concrete products or structures were considered for its application. Experiment was carried out for the bending strength of aggregate (2.45 of cement) by weight and F-fiber (density of 1.45, volume ratio to all of the aggregate and the cement). Whereas the specimen containing 1% F-fiber showed the bending strength 23% higher than that without F-fiber after curing far 28 days, the one with 0.5% F-fiber did not give any change. It could be found, therefore, that the minimum mixing amount should be larger than 0.5% fur the strength reinforcement. One of the reinforcing concrete product, bench flume, containing 1% F-fiber showed 21% increment of bending strength In contrast to that without F-fiber.
