英文摘要	Aiming at the extrusive problem of poor durability of concrete in saline soil area of western China, the indoor accelerated life test of concrete was designed to simulate natural environment, including halide corrosion, wet and dry cycle, freeze-thaw cycle and solar radiation. The dynamic modulus of elasticity was adopted as the to failure threshold to evaluate the durability of concrete, and the accelerated life data of concrete were obtained. Based on the three-parameter Weibull distribution, the probability analysis software was employed to analyze and predict the life data, and the distribution overview plot-arbitrary cens of accelerated life was acquired. It could be found from the results that the sample points of accelerated life data could be well fitted by three-parameter Weibull distribution. Moreover, the failure time of concrete durability degradation and reliability of accelerated degradation process could be directly reflected by its threshold parameter and distribution overview plot-arbitrary cens, respectively, which provides a novel reliability basis for durability evaluation of concrete. © 2019, Materials Review Magazine.
