Abstract: 
In 1982, reinforced concrete test beams were suspended in a temperate marine splash zone beneath a berth in Fremantle, Western Australia. The concretes used in these specimens included Ordinary Portland cement alone or with silica fume or ground granulated blastfurnace slag (GGBS) replacement. During 2001 the test beams were subjected to resistivity, half-cell potential and LPR corrosion rate measurements. Samples of concrete were removed to determine the depth of chloride penetration. The chloride diffusion coefficient and sorptivity of uncontaminated concrete were also measured. Some data on chloride penetration had been previously obtained after two and six years exposure. The measured chloride penetration profiles are compared with some commonly used service life prediction models to assess the validity of their predictions based on the initial information that would have been available at the time the specimens were cast.
