Service Life Prediction of SFRC Corbels Subjected to Chloride-Induced Corrosion

Abstract

in addition to the resistance of structures, the service life of reinforced concrete structures is also influenced by chloride-induced corrosions. Due to the importance of effect of corrosion, in this paper, an effort is made to determine the service life of steel fiber reinforced concrete (SFRC) corbels considering chloride-induced corrosion. The approach employed herein, is based upon an analytical formulation of resistance for these components

the effect of corrosion due to chloride penetration through reinforced concrete is taken into account by applying Ficks second law of diffusion. Finally, for the selected SFRC corbels, the effects of initial chloride concentration on the surface of concrete and the thickness of concrete cover on the load carrying capacity of steel fiber reinforced concrete corbels and their service lives are investigated.

Corrosion in reinforced concrete structures due to aggressive chloride contamination, is a major contributing factor resulting in deterioration of resistance in these structures
