Shotcrete is widely used in underground engineering, such as subway, road, or railway tunnels and public sewers.In this study, setting time, permeability, durability performance, and mechanical properties of shotcrete were evaluated before and after corrosion damage occurs.This experiment was completed in two phases.In the first phase, setting time of cement pastes with an accelerator, mechanical properties in different hydration ages,and permeability of shotcrete for 90 days of curing were investigated.In the second phase, durability of shotcrete with 10% fly ash and 0.64 vt.% steel fiber was investigated through environmental corrosion-related processes, including freeze-thaw cycle, accelerated carbonation test, sulfate attack, and chloride ion diffusion.Results showed that ordinary shotcrete exhibited greater durability properties, except carbonation and chloride ion diffusion, than ordinary concrete with the same mixture.Thus, steel fiber (steel fiber-reinforced shotcrete) not only provided a denser microstructure in shotcrete matrix but also significantly improved early-age compressive and splitting tensile strengths, permeability, and durability of shotcrete.
