This research investigates the relationship between workability and compressive strength of Self-Compacting Concrete (SCC), which can flow and compact under its own weight without segregation. Four SCC mixes with varying water/powder ratios (0.35 to 0.50) and superplasticizer dosages (7, 8.5, and 10 L/m³) were studied, with 15% cement replaced by fly ash. Workability was assessed using slump flow, V-funnel, and L-box tests, and compressive strength was measured.Results indicate that increasing superplasticizer dosage improves both workability and compressive strength. The SCC4 mix with the lowest W/P ratio (0.35) showed the highest compressive strength, while the SCC3 mix (W/P 0.50) had the best workability. The SCC2 mix achieved optimal balance between strength and workability. The study concludes that the relationship between workability and compressive strength in SCC is nonlinear.
