Abstract
Through the corrosion-damaged experiment of steel fiber reinforced concrete (SFRC) in simulation domestic sewage, the corrosion resistance of SFRC placed in domestic sewage were investigated. The results show that high concentration domestic sewage would cause the properties of SFRC to deteriorate, and the corrosion coefficients of compressive and flexural strength of SFRC decrease gradually with the increase of corroding age. The steel fiber can not inhibit obviously the degradation of concrete compressive and flexural strength unless the steel fiber volume fraction is more than 1.0%. The size effect on compressive and flexural strength of SFRC after corroding in domestic sewage is existent.
