英文摘要	An accelerated failure test of concrete was conducted in a special natural environment, and accelerated life data were obtained. Firstly, the Weibull distribution function was used to model the degradation process by combining the life data.Then, the parametric estimation of the Weibull distribution was proposed by using different parameter estimation methods. Finally, the reliability and probability density functions of service life were established.The results showed that the Weibull distribution can describe the durability degradation of concrete specimens effectively. By using this method, the accelerated life reliability function of concrete can reflect the service life of the specimen directly, and the experimental value is in good agreement with the lifetime prediction. In applying the parameter estimation method, the least square (LSE) method and maximum likelihood estimation (MLE) methods are suitable to obtain complete life data for small samples. This provides a direct and effective method to estimate the parameters for lifetime prediction and reliability evaluation of the accelerated failure test of concrete. © 2020, The Editorial Board of Journal of Basic Science and Engineering.
