| 摘 要： | 对掺入磨细掺合料的再生混凝土的抗压强度及抗渗性、抗冻性、抗碳化等耐久性能进行了研究。结果表明，适量磨细粉煤灰掺入再生混凝土中对混凝土抗压强度及耐久性能影响不大；将磨细粉煤灰与矿渣混掺可以发挥复合效应，提高掺合料的活性，改善再生混凝土的性能。

| Abstract: | The properties of recycled concrete incorporating ground minerial admixture , including compressive strength and durability such as permeability , freezing - thaw resistance and carbonation of this kind of concrete were studied. The test results showed that incorporating suitable amount of ground fly ash could improve the compressive strength and durability of concrete . When ground fly ash with blast furnace slog were added into concrete together , the performance of recycled concrete could be improved further due to the synergistic effect. |
