采用ASTM C1202法研究了冻融对掺合料再生混凝土抗氯离子渗透性能的影响规律.试验结果表明,冻融对粉煤灰再生混凝土抗氯离子渗透性能的影响比较大,随着冻融次数的增加,粉煤灰再生混凝土抗氯离子渗透能力逐渐减弱.冻融初期,冻融对粉煤灰-石灰粉再生混凝土抗氯离子渗透性能影响较小;冻融次数超过10次后,随着冻融次数的增加,冻融对粉煤灰-石灰粉再生混凝土抗氯离子渗透性能影响逐渐增强.

The rapid chloride permeability test method (ASTM C1202) was used to research influences of freeze-thaw on anti-chloride-permeability performances of recycled concrete. The results showed that freeze-thaw cycle has clear implications for the anti-chloride-permeability performances of fly ash recycled concrete. With the increase of freeze-thaw times, the capacity of resistance to chloride ion permeability of fly ash recycled concrete decreased gradually. At the early stage of freeze-thaw, the ability of anti-chloride ion permeability of recycled concrete mixed with fly ash and lime powder is less affected by freeze-thaw. After 10 times freeze-thaw cycle, freeze-thaw has an ever-increasing impact on the anti-chloride ion ability of recycled concrete mixed with fly ash and lime powder.
