Abstract

This study investigates the effects of glass, basalt, and carbon fibers on the fresh, mechanical, and durability properties of self-compacting concrete (SCC). An M30-grade SCC mix was reinforced with 12 mm fibers at volume fractions of 0.10% to 0.30%. Fresh properties were assessed via slump flow, T₅₀₀, V-funnel, and L-box tests per EFNARC guidelines, while hardened performance was evaluated through compressive strength, split tensile strength, toughness, and fracture energy. Durability was examined via water absorption and sorptivity tests. Results indicate that basalt fiber at an optimum dosage provides the best balance of workability, strength enhancement, durability, and cost-effectiveness. Carbon fibers showed the highest strength gains but at greater expense, while glass fibers offered moderate performance. Overall, basalt fiber is identified as the most suitable reinforcement for producing high-performance self-compacting concrete, and the findings provide practical guidance for developing durable and sustainable SCC for modern infrastructure applications.
