Abstract

When compared to traditional concrete, self-compacting concrete (SCC) is known for its better workability, durability, and mechanical performance. It also has the advantage of not requiring vibration. Its tensile strength, ductility, and fracture resistance are further improved by the addition of discontinuous fibers. The impact of carbon, glass, and basalt fibers at different volume fractions (0.0–0.3%) on the mechanical, fresh, and durability characteristics of M30 grade SCC is examined in this work. According to the results, the inclusion of fiber had a substantial impact on workability. Glass fiber blends maintained better flow, whereas carbon fiber mixes exhibited the most drop because of their higher water absorption. The ideal dosages—0.15% carbon, 0.20% glass, and 0.25% basalt—provided significant increases in compressive and flexural strength in the hardened state. Glass guaranteed economy and early-age workability, carbon produced the greatest strength improvements, and basalt fiber provided the best balanced performance overall.
