This paper is a continuous study that outlines Self Compacting Concrete (SCC) behavior on high strength concrete with nickel slag as fine aggregate. The percentage of nickel slag substitution as fine aggregate varies from 0% to 100% with an increase of 25%. This laboratory study aims to obtain the effect of seawater curing on the concrete compressive strength. The specimens immersed in seawater for 220 days will provide a SCC behavior assessment towards seawater immersion. The results obtained show that concrete with 25% nickel slag gives the most maximum effect. Compared to concrete without slag, SCC with 25% nickel slag has a higher compressive strength of 17%. Besides, the slump test also showed good condition. All specimens using nickel slag in seawater immersion show greater strength when compared to non-slag concrete. This means that concrete is very suitable at a curing age of 220 days when substituted with nickel slag. The mixture using nickel slag of 100% (SCC100 specimen) illustrates a reasonably stable strength from 28 days of immersion.
