| 英文摘要 | External sulfate attack (sulfate attack hereafter) is one of the most important factors that influences the long-term durability of concrete structures when exposed to aggressive environments. Concrete can expand, crack, and lose strength as a result of sulfate attack. This paper presents the results from an experimental investigation on nano-CaCO3-modified concrete under sulfate attack. The specimens were exposed to a partially submerged condition in 10% Na2SO4 solution. The mechanical and durability performance were evaluated based on durability evaluation parameters. Eventually, the Birnbaum-Saunders (B-S) life prediction model was used to assess the long-term performance of the tested mixtures. The results show that when the content of nano-CaCO3 is 1%, the resistance of concrete to sulfate attack is greatly increased, and the service life of concrete structures is increased significantly. Moreover, using a reliability approach, the proposed model can effectively describe the degradation process of concrete under sulfate attack. |
