Abstract :
Based on the compressive strength, flexural strength and freeze-thaw test of the steel fiber reinforced concrete (SFRC) mixed with fly ash, the influence of different fly ash mixing on the basic mechanical properties of steel fiber reinforced concrete and freeze-thaw effect were analyzed, and the thawing mechanism of steel fiber reinforced concrete with high mixing of fly ash was discussed. The test results presented that the mixing of steel fiber and fly ash can significantly improve the spalling resistance and freezing-thawing properties. With the increasing of fly ash, the effect of freeze-thaw on steel fiber reinforced concrete is reduced.
