Properties on the Freeze-Thaw Resistance of High Performance Concrete Using Fibers and Mineral Admixtures

For the examination of freeze-thaw action, which is a durability deterioration factor of concrete, this study aimed to investigate the deterioration of concrete under the freeze-thaw condition of the high-performance concrete manufactured using both fiber and mineral admixture. After 300 freeze-thaw cycles, the relative dynamic moduli of the FA-PP-02 and SF-01 specimens were 85.7% and above 92.9%, respectively, and the compressive strengths of the FA-PP-02 and GA-Ny-03 specimens were 61% and above 83%, respectively. Among the high-performance concrete specimens, the specimen that used only Steel Fiber and the specimen that used both Garnet and Nylon showed the most outstanding freeze-thaw resistance.
