A Study on Steel Fiber Influence to Rebar Corrosion in Concrete

Abstract:

In dry-wet cycle chloride environment, the corrosion potential of the SFRC specimens is stable between-300mV to-400mV. And the common concrete specimens were about-500mV, adding steel fibers is higher corrosion potential and lower the corrosion possibility. Steel fiber has effective action on the controlling rebar corrosion and concrete crack. There were no cracks on all the surface of the SFRC specimens. Adding Steel fiber in concrete composed to be a corrosion cell as sacrificial anodes to protected steel rebar as cathode, in some degree to postpone rebar corrosion beginning time and increasing the structure services life.
