The presence of different filler materials in the SCC mixture is a major change in Self-Compacting Concrete (SCC) compared to ordinary concrete. The use of filler materials in SCC improves workability and reduces cement content. In the existing work, an investigational study has been carried out by using two filler waste materials, Marble Powder (MP) and Lime Powder (LP), to increase the fresh and hardened property of SCC. Different tests were performed using three replacement levels of 0, 10, and 15% of cement along with fine aggregate to the total aggregate ratio, ranging from 0.50, 0.54, and 0.56 to evaluate the fresh and hardened property of SCC. M30 concrete was designed and investigated for the same parameters with the use of LP and MP as non-pozzolanic fillers in SCC. The presence of filler types and content has a significant influence on flow behavior and the better deformability obtained in SCC samples. The test results show that fine aggregate to the total aggregate ratio has substantially affected the fresh and hardened property of SCC in the presence of filler materials. The compressive strength at a higher fine aggregate to the total aggregate ratio (0.56) and higher replacement (15%) decreases compared to 0.50 and 0.54 ratios of the same replacement. Also at 0.54 coarse aggregates to fine aggregate ratio, medium content of coarse aggregate and presence of filler provide better lubrication and enhance flowability, passing ability, segregation, and bleeding resistance. All samples of M30 concrete have satisfied workability criteria. The results are well matched with the SCC guideline (EFNARK 2005).
