Study on the Weakening Performance of Fiber Concrete under the Action of Acid Rain-sewage Coupling Erosion

Abstract

Unfavorable environments such as acid rain corrosion and sewage erosion will have a great impact on the mechanical properties and durability of concrete structures. In order to further explore the weakening performance of concrete structures in harsh environments such as acid rain and sewage, plain concrete, basalt concrete with 0.08%, 0.1%, and 0.12% fiber content were adopted for comparative analysis. The weakening of compressive and flexural strength of concrete with different fiber content under sewage erosion and acid rain corrosion were investigated. The results of this paper can provide reference value for further research on the deterioration performance and life prediction of structures under long service life.
