Abstract：Coupled tests of sulfate corrosion and freeze-thaw cycling were conducted on concrete with different dosages of multi-walled carbon nanotubes(MWCNTs).The durability degradation behavior of MWCNTs concrete was investigated.Meanwhile,the reliability analysis model of MWCNTs concrete was established based on Weibull distribution.The results indicate that the incorporation of MWCNTs effectively enhances the salt freezing resistance of concrete.After 200 coupled cycles,the compressive strength of concrete with 0.05%MWCNTs is 14.5%higher than that of plain concrete,achieving the best improvement effect on salt freezing resistance under this dosage.The proposed reliability model based on Weibull distribution can predict the deterioration of MWCNTs concrete in a salt freezing environment,and the predicted results are in good agreement with the experimental data.
