Abstract

The cracks in concrete structures will accelerate the ingression of chloride ions. And due to global warming, chloride diffusivity and rate of chloride penetration will also increase. Previous studies mainly focus on the effect of global warming on chloride ingress, but ignore the changing of sea level and surface chloride concentration. This study presents a numerical procedure to analysis the service life of cracked concrete considering global warming and sea level rise. First, the equivalent chloride diffusion coefficient of cracked concrete is determined considering sound zone and cracked zone. The influence of crack width and crack interspace on equivalent chloride diffusivity is clarified. The effect of sea level rise on surface chloride concentration is described using Bruun rule. Second, based on probability method, the service life of cracked concrete is predicted. The analysis results show that the effect of sea level rise on service life is comparable with that of global warming. The reduction ratio of service life is almost proportional to previous service life of concrete. When the previous service life is 50 years, after considering temperature rise and sea level rise, the reduction of previous service life is about 6%.
