Abstract: Prediction of chloride ingress into concrete is an important part of durability design of reinforced concrete structures exposed to chloride containing environment.
This paper presents experimentally based design parameters for Portland cement concretes with and without silica fume and fly ash in marine atmospheric and submersed South Scandinavian environment. The design parameters are based on sequential measurements of 86 chloride profiles taken over ten years from 13 different types of concrete.
The design parameters provide the input for an analytical model for chloride profiles as function of depth and time, when both the surface chloride concentration and the diffusion coefficient are allowed to vary in time. The model is presented in a companion paper.
