| 摘 要： | 对粗骨料取代率为100％的再生混凝土氯离子渗透性进行了试验研究，分析了不同强度等级下再生混凝土的氯离子渗透性，并与相同强度等级的普通混凝土进行了对比研究。结果表明：随着强度的提高，再生混凝土的抗氯离子渗透性相应提高；在相同强度等级下，再生混凝土与普通混凝土的氯离子渗透性相差不大。

| Abstract: | The permeability of chloride ion of recycled aggregate concrete(RAC) with 100% replacement percentage of recycled coarse aggregate(RCA) is investigated experimentally.The relationship between chloride permeability and the compressive strength of RAC is studied,and the chloride penetration of RAC is compared with that of normal aggregate concrete(NAC).The results show that the chloride impermeability of RAC increased with the increasing of the compressive strength,and the penetration of chloride ion of RAC i... |
