"Comprehensive Performance Evaluation of M30 Grade Self-Compacting Concrete (SCC) and Normal Conventional Concrete (NCC) Reinforced with Steel Fibers and Ternary Supplementary Cementitious Materials

This study investigates the performance of M30-grade Self-Compacting Concrete (SCC) and Normal Conventional Concrete (NCC) incorporating steel fibers and ternary blends of Supplementary Cementitious Materials (SCMs), specifically Fly Ash (FA), Ground Granulated Blast Furnace Slag (GGBS), and Silica Fume (SF). The research focuses on evaluating the influence of these materials on the fresh and hardened properties of both SCC and NCC. A total of 20 mix combinations were designed with varying percentages of Ordinary Portland Cement (OPC), ternary SCMs (10% FA, 15% GGBS, 5% SF), steel fibers (0.5%, 1.0%, and 1.5%), superplasticizer (SP), and viscosity-modifying agent (VMA). The performance of these mixes was assessed in terms of workability, compressive strength, flexural strength, and durability. Results indicate that the incorporation of SCMs and steel fibers enhances the mechanical properties of both SCC and NCC, with SCC demonstrating superior strength and workability compared to NCC. This research provides valuable insights into the benefits of using SCMs and steel fibers in concrete, offering potential for sustainable and high-performance applications in the construction industry.
