Conventional concrete frequently has issues with appropriate compaction in thin sections or regions of dense reinforcement, which results in a significant amount of trapped air the concrete's strength and longevity. Self-Compacting Concrete (SCC), which was created to compact under its own mass, can reduce this issue. Fresh concrete must have a high fluidity and good cohesion for this application. It is suggested to employ fine components in fresh concrete of grade M30, like fly ash (to replace 40% of the cement), superplasticizer (viscocrete), and viscosity modifying agent (stabiliser 4R), while also researching the characteristics of SCC concrete. In this study, slump flow tests, U-box tests, L-box tests, and V-funnel tests were used to determine the properties of self-compacting concrete with or without steel fibre
