This research describes methods to make effective use of the scrapped Fiber Reinforced Plastics (FRP) for admixture of mortar and concrete. The mixing method and the flexural property of discontinuous fiber reinforced mortar used the glass fiber which was reproduced by to reclaim and decompose the scrapped FRP with the aerial pulverizer were experimentally investigated.From this experiment it was found that the flexural strength and the toughness of mortar were improved with increase of the fiber content. Furthermore, it is possible to restrain the decrease of mortar strength with the ages by glass fiber of an alkali deterioration through replacing cement with blast-furnace slag by 30% to 50%.

本研究描述了有效利用废弃纤维增强塑料（FRP）来掺合砂浆和混凝土的方法。采用航空粉碎机回收分解报废玻璃钢再生玻璃纤维，对不连续纤维增强砂浆的混合方法和弯曲性能进行了试验研究。通过该试验发现，砂浆的弯曲强度和韧性随纤维含量的增加而改善。此外，通过用高炉矿渣代替水泥，可以将碱劣化的玻璃纤维随使用年限而导致的砂浆强度降低抑制30％至50％。
