Self-Compacting Concrete (SCC) is a form of special concrete that offers economic and technical benefits over normal concrete. In recent years, application of SCC is increasing in various precast and ready-mix industry. SCC in fresh state, consolidated by its own weight even in the presence of congestion of reinforcement while maintaining homogeneity. Most of the mix proportioning methods suggest a robust mix-design method, which is different from the mix design of normal concrete. In the present study, an experimental work was carried out in order to develop 6 different SCC mixes, three each by using modified Indian Standard (IS:10262-2009) method and volume fraction method. Three different volumes of paste (V_p) (0.33, 0.35, and 0.37) with water contents (195, 205, and 215 lt/m³) and different cement contents along with GGBS as filler was used. The results indicate that the compressive strength of SCC increases with paste content for the same w/c ratio in both mix design methods. The existence of optimal value of V_p was observed, which was independent of the water content, indicating the importance of V_p along with w/c ratio in the mix design. The SCC mixes developed by volume fraction method showed better performance when compared to mix design developed by modified IS method.
