The performance of CEM I, CEM III/A and CEM II/B-V reinforced concrete slabs which have been exposed to a marine environment for 18 years is presented. Performance is assessed in terms of porosity, degree of saturation, chloride concentration and electrical resistivity gradients evaluated through the surface 150mm; the condition of the embedded steel was evaluated using electrochemical techniques. Based on the parameters related to chloride transport, two new environmental factors were introduced into the ClinConc model to predict chloride ingress into unsaturated concrete. A monitoring system is also presented enabling remote interrogation of those slabs located at the marine exposure site.
