采用50℃热水加速老化的方法，以抗折强度的变化为考察目标，研究了废砖取代天然砂\粉煤灰取代水泥对 GRC 耐久性的影响。结果表明，废砖取代 GRC 中天然砂对其耐久性有提高作用；粉煤灰在废砖及天然砂混合骨料 GRC 体系中对玻璃纤维的“保护”作用较在天然砂骨料 GRC 体系中强；废砖以45%的体积取代率取代天然砂，较之粉煤灰以20%质量取代率取代水泥对 GRC 的耐久性改善作用大，二者同时取代时较之单独取代效果好。

By using the method of accelerating GRC ageing, the effects of waste brick and fly ash on the durability of GRC are researched. The results show that the durability of GRC can be improved when natural sand in GRC is replaced by waste brick. The improving effect of fly ash on the durability of GRC with waste brick aggregate is greater than the one with natural sand aggregate. The improving effect on the durability of GRC with natural sand replaced by 45% waste brick (volume fraction), is greater than the one with P?O cement replaced by 20% fly ash(mass fraction), and the effect is greater when natural sand and cement are replaced simultaneously by waste brick and fly ash with the replacement rate mentioned above.
