Abstract: Concrete is the most commonly used construction material. Concrete exhibits flexibility as it can be easily moulded and shaped. Despite its flexibility, as the infrastructure design progresses, the range of concrete during the casting process becomes limited due to congested reinforcement. This kind of problem can be solved with concrete innovations, such as Self-Compacting Concrete (SCC). In making SCC, additional material is needed to help produce high workability of concrete, but still concerned with the strength of the concrete itself. The purpose of this study is to determine the effect of the addition of superplasticizer (with 1%, 1.5%, and 2% variations and silica fume additives 8% by weight of cement. The results showed that the addition of superplasticizer can help improve the workability of SCC, while silica fume does not have a significant effect on the workability of concrete. The highest compressive strength in this study was obtained in the variation without added ingredients, with a compressive strength of 52.796 MPa, and the lowest compressive strength was obtained in the variation of 2% superplasticizer at 20.865 MPa. This decrease occurs due to segregation caused by overdosing of superplasticizer, which disrupts the function of silica fume and causes a decrease in concrete performance. This research shows the importance of adjusting the content of superplasticizer and silica fume in the making of SCC so that there is a balance of the functions of both additives.
