Deicer salt scaling resistance of steel-fiber-reinforced concrete

This project is part of a global research program aimed at studying the durability of steel-fiber-reinforced concrete exposed to severe winter conditions. It was carried out to determine if the use of steel fibers can have a significant influence on the deicer salt scaling resistance of concrete. Sixteen steel-fiber-reinforced concrete mixtures were investigated. The test variables were the water/binder ratio, the use of silica fume, the type of fiber and the quality of the air-void network. The results of the tests show that the fibers have no apparent influence on the deicer salt scaling resistance of concrete. Furthermore, it has been observed that a very small difference in the minimal freezing temperature could have a great influence on the deicer salt scaling resistance.
