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%.

本文介绍了如何有效地利用废弃的纤维增强塑料（FRP）作为砂浆和混凝土的掺合料。对用再生玻璃纤维回收分解废弃玻璃钢的不连续纤维增强砂浆的配制方法和抗折性能进行了试验研究，发现随着纤维掺量的增加，砂浆的抗折强度和韧性均有所提高。此外，通过用高炉矿渣代替水泥30%至50%，可以抑制碱劣化的玻璃纤维引起的砂浆强度随龄期的降低。
