Abstract EN
The chloride diffusion coefficient is the most important parameter when predicting chloride ingress in concrete.
This paper proposed a model for calculating the chloride diffusion coefficient of steel fiber reinforced concrete (SFRC).
Considering the concrete structures in service are usually subjected to external loads, the effect of bending load was discussed and expressed with a stress factor ks in the model.
The chloride diffusion coefficient of cement paste was calculated with capillary porosity and then used to predict the chloride diffusion coefficient of SFRC.
Some factors in the model were determined with experimental results.
Chloride bulk diffusion tests were performed on SFRC and plain concrete (without fiber) specimens under bending load.
SFRC showed slightly better chloride resistance for unstressed specimens.
The compressive stress decreased the chloride diffusion coefficient of SFRC, while it caused no change in plain concrete.
For the tensile zone, the chloride resistance of concrete was improved significantly by adding steel fibers.
Overall, SFRC performed better chloride resistance, especially under bending load.
The proposed model provides a simple approach for calculating the chloride diffusion coefficient of SFRC under bending load.
