Low-carbon concrete (LCC) uses supplementary cementitious material (SCM) to partially replace cement as a method for reducing its carbon footprint. Previous laboratory and field studies had provided substantial support and experience for using LCC in marine structures, which are the most susceptible to chloride-induced corrosion. Some short-term test methods have provided reliable assessment of the ability of LCC to resist chloride penetration, but the long-term chloride penetration depends on a great many factors and thus could differ from the results obtained from laboratory tests. However, the lack of a correlation between the data from short-term and long-term tests has limited the use of abundant laboratory results for service life design of LCC. This study presents an overview of results obtained when LCCs were exposed to chlorides. The key outcome of this study is a broader synthesis of the available data regarding the relationship between the mix design and the performance of LCCs in various chloride environments, which helps find the possible correlation and fully appreciate the value of the short-term tests.
