Self-compacting concrete (SCC) is a high-performance concrete and it has very unique property to flow under its own weight and do not require vibrators. The use of admixtures can further improve the properties of SCC. The study aims to improve workability and compressive strength of SCC. Four types of admixtures were used in this study: fly ash, silica fume, red brick powder and rice ash husk. Fresh properties or workability of self-compacting concrete was tested using the Slump flow, U-box test, L-box test and V-funnel test. Compressive strength was estimated at ages 7 and 28 days of casted cube by compression test machine.
