One of the unique concretes that is highly valued in the modern construction industries is Self-Compacting Concrete (SCC). One of the main uses of SCC is that it may be filled without vibration or manual compaction in the formwork of a heavily reinforced structure. However, SCC lacks conventional mix design techniques and internationally recognised testing methods for the qualities of its fresh concrete. This limits SCC's growth in the construction industry. Additionally, SCC calls for higher amounts of fine aggregate and binder, which raises the price of concrete. The flexural properties are improved by the use of fibrous materials. Using steel fibres in normally vibrated concrete has a number of drawbacks (NVC). The density of steel fibres is larger than that of other composites found in the concrete, which might cause isolation of the steel fibres from other composites during incorrect vibration. This is one of the main disadvantages of employing steel fibres in NVC.

In phase-I the mix proportion was arrived for M50 grade of concrete using Nan-Su proposed mix design method.
