Abstract：The purpose of this article is to study the durability of Steel Fiber Reinforced Concrete(SFRC) under wastewater and watering-drying cycle coupling effect from the perspective of compressive strength, flexural strength, corrosion coefficient of compressive strength, corrosion coefficient of flexural strength. Test results showed that durability test efficiency can be improved by increasing solution concentration, decreasing specimen size and watering-drying cycle; The relationship between corrosion extent and test age is nonlinear under wastewater and watering-drying cycle coupling effect; The bigger steel fiber volume fraction, the better SFRC’s resistance to corrosion; The corrosion extent to SFRC is stronger, industrial effluent than sewage; The test results can be summarized exactly with corrosion coefficient of compressive strength and corrosion coefficient of flexural strength.

Key Words: SFRC, Wastewater, Drying and wetting cycle, Durability experiment
