Abstract: The purpose of this study was to assess the suitability of mixes containing ground granulated blast furnace slag (GGBS) along with Portland cement mixes recommended in BS 8500- 1:2015for the marine environment for both 50 and 100 years of service life. As the damage caused by chloride-induced corrosion can be expensive to repair, there is a need to use suitable concrete mixes and predict the service life of these concretes in marine structures. This study has reviewed BS 8500-1:2015 mixes containing GGBS, using the software Life- 365TM to predict the service lives of the concretes exposed to various sea water exposure conditions (XS). The results showed that the service lives outlined in the standard were not achieved by all mixes. A close examination of data from the models was then carried out to establish the influence of various input parameters on the service life, viz. water-binder ratio (w/b), GGBS content and depth of cover. By comparing the data from the model with experimental data, it was also demonstrated that Life-365TM is a valuable tool to predict the service life of concretes containing GGBS in marine environments provided appropriate input parameters are used.
