摘要：

In order to investigate the corrosive resistance of partially steel fiber reinforced concrete (PSFRC), the flexural toughness experiment of nine specimens subjected to corrosion by alternating wet and dry cycles in a simulated marine environment were conducted, which aims at investigating the influence of corrosion time, steel fiber volume fraction and SFRC thickness on PSFRC toughness. The experimental results show that both the mechanical performance and ductile characteristics of PSFRC get worse due to corrosion even if increasing the steel fiber volume. Additionally, the influence of steel fiber content on the toughness and ultimate load are greater than that of PSFRC thickness (t). The increase of 56.6 % and 171 % may be obtained to the mean ultimate load and I-10 with the increase of steel fiber volume from 0.5 % to 2.0 %. This paper could offer a reference to the application of PSFRC in sea-water environment.
