Steel fiber concrete shows good corrosion resistance in air, sewage and seawater. The carbonization depth of specimens exposed to sewage and seawater is less than 100 years. Only the surface steel fibers produce rust spots, and the internal steel fibers are not rusted, unlike ordinary steel fiber concrete. After the steel bars in reinforced concrete corrode, the volume of the rust layer expands and the concrete bulges and cracks. In addition to the fact that steel fiber concrete has no significant change in impermeability compared to ordinary concrete, steel fiber concrete has good crack resistance and integrity, so it has freeze-thaw resistance, heat resistance, abrasion resistance, cavitation resistance and corrosion resistance. sex has improved significantly. After repeated freeze-thaw cycles, the compressive and flexural strength of the mixed steel fiber concrete decreased by about 10%, while that of ordinary concrete with the same other conditions dropped by more than 1%. After repeated freeze-thaw cycles, the steel fiber concrete specimens remained intact. The wear resistance loss of steel fiber concrete with a dosage of 0 and a strength grade of 0 is lower than that of ordinary concrete. The cavitation resistance of high-strength concrete mixed with steel fibers is higher than that of high-strength concrete with the same conditions.
