| 摘 要： | 研究了高性能再生混凝土的抗渗透性、抗裂性以及抗冻性等耐久性.结果显示,采用粉煤灰、磨细矿渣粉配制的高性能再生混凝土具备良好的抗渗透性、抗裂性和抗冻性,降低水胶比可适当提高再生混凝土的抗渗透性、抗冻性,但对抗裂性不利,再生集料降低了混凝土的抗裂性,对抗渗透性、抗冻性的劣化影响不显著.

| Abstract: | Of the impermeability of recycled concrete performance,such as crack resistance and durability of frost resistance.The results showed that using fly ash,ground slag,high-performance recycled concrete powder preparation have a good anti-permeability,crack resistance and frost resistance,lower water-cement ratio may be appropriate to improve the impermeability of recycled concrete,frost resistance,But bad crack resistance,recycled aggregate concrete decreased crack resistance against penetration,frost resistance of the deterioration was not significant. |

| Keywords: | Recycled concrete anti-permeability anti-cracking crack of frost resistance |
