Abstract

Abstract

In order to study the Cl-migration under freeze-thaw cycle and the freeze-deicing salt scaling resistance of polypropylene fiber concrete with different volume,indoor artificial method was used to simulate freeze-thaw cycle.The results indicated that the scaled mass and relative dynamic modulus of elasticity loss decrease with the volume of fiber increasing,Cl-concentration had a enrichment near the sample surface,adding 0.1% PPF into concrete had the prefect resistance of deicer-frost scaling.More fibers could delay the development of cracks,but that would reduce the inner density of concrete.
