Abstract
In this study, the effects of the kind and replacements of mineral admixtures on the properties of offshore concrete were investigated. The results showed that the compressive strength of concrete made with fly ash (FA) was 16.1~24.1% higher than that of concrete made with FA and silica fume (SF). The concrete made with ground granulated blast-furnace slag (GGBS) showed the lowest chloride ion diffusion coefficient. However, GGBS concrete showed a higher length change than ordinary portland cement (OPC) concrete. Furthermore, the low productivity of high durable offshore concrete should be considered because it has a low apparent yield value and high plastic viscosity.
