英文摘要	In order to increase the utilisation rate of waste ceramics and recycled aggregate, and improve the poor durability of recycled concrete in Salt Lake area, a kind of ceramic-recycled gradient concrete is proposed. The ultrasonic wave velocity and mass loss of each specimen are tested to study the durability of ceramic regenerated gradient concrete in Salt Lake area. The fitting function of ceramic regenerated gradient concrete under two factors is established by MATLAB. The degradation model of quality loss and ultrasonic wave velocity is established by the Wiener random process. The results show that the durability of ceramic regenerated gradient concrete increases with the increase of the thickness of external protective material. Furthermore, the ultrasonic wave velocity is used as the evaluation index, which is more sensitive than the quality loss evaluation index. The Wiener random function can establish the reliability of the residual life of the specimens under the condition that the part of the life of the specimens has been measured. The predicted results are in good agreement with the actual measurements. © 2020, © 2020 Engineers Australia.
