英文摘要	Sulfate erosion is one of the important factors causing the decline of concrete durability, and it is also one of the most environmentally damaging and most influential types of environmental erosion. In view of the problem that the durability of fibre-reinforced concrete decreased due to sulfate attack, according to the natural environmental conditions in western China, the rapid corrosion test of fibre (layered hybrid) concrete was carried out using the test method of accelerated erosion in saturated solution immersion. The loss of strength, mass and relative dynamic elastic modulus was studied as the law of durability degradation. A reliability analysis method for the residual life of sulfate-resistant concrete based on Wiener distribution is proposed. The dynamic elastic modulus was selected as the key degradation indicator to establish the fibre concrete reliability model and for life prediction. The results show that the layered hybrid fibre-reinforced concrete has stronger erosion resistance. Among the reliability evaluation parameters, the relative dynamic elastic modulus is more sensitive than the mass loss. The Wiener distribution process can effectively describe the degradation law of fibre concrete performance. Based on the experimental data, the residual life reliability model established by this method can directly reflect the relationship between the reliability of the test piece and the corrosion time and can reflect the remaining life of the test piece. © 2020 ICE Publishing: All rights reserved.
