Abstract: In order to study the effect of salt freezing environment on the mechanical properties of recycled aggregate concrete(RAC), the strength grade, the number of freeze-thaw cycles and the eroded salt type were used as test variables, and the macroscopic and microscopic tests were combined. The deterioration mechanism of RAC and normal aggregate concrete(NAC)after salt freezing cycle was analyzed. Based on the relative dynamic elastic modulus of RAC under salt freezing cycle test, the Wiener random process was used to model and analyze the change rule of reliability, and the service life of RAC in salt freezing environment was predicted. The results showed that the salt freezing resistance of RAC was worse than that of NAC, and the higher the strength grade of RAC, the better the salt freezing resistance. The loss rate of dynamic elastic modulus of 3.7% mass fraction Na2SO4 group was only 1.72% before 60 salt freezing cycles, and the loss rate of dynamic elastic modulus of RAC decreased rapidly after 90 salt freezing cycles due to the damage accumulation of salt freezing resistance, reaching 17.16 %. Microscopic analysis found that after the salt freezing cycle, the lower the RAC strength rating, the looser the internal structure was after salt freezing, and the larger the crack width. According to the model analysis of Wiener random process, the reliability duration of RC50-C model was the longest, and the estimated value of frost resistance durability life in North China could reach 53 years.

Key words: recycled aggregate concrete, salt freezing cycle, durability, Wiener random process, life prediction
