In this paper models for environmental actions on reinforced concrete structures exposed to chlorides are proposed. The models are based on the DuraCrete chloride ingress model and in the paper they are briefly presented and examples are given of how some of the parameters in the models can be quantified. Service life predictions have been made to exemplify how the models for environmental actions influence the service life for reinforced concrete structures in different marine exposure conditions. The results from the service life predictions show the consequences of the modelling of the environmental actions in these exposure conditions. They also show on the possibilities to optimise the design of reinforced concrete structures exposed in different exposure conditions with respect to durability. This can be made for example by appropriate choices of concrete compositions and covers based on the service life predictions.
