STRENGTH DEVELOPMENT OF CONCRETE REINFORCED WITH BASALT FIBERS: A COMPREHENSIVE REVIEW

Abstract

Basalt fiber reinforced concrete (BFRC) represents an emerging construction material that combines the durability of basalt fibers with cement-based matrices to enhance mechanical performance. This comprehensive review synthesizes current research on strength development mechanisms in BFRC, encompassing early-age and long-term strength evolution, compressive and tensile properties, and the influence of fiber parameters on structural performance. Incorporating an optimal amount of basalt fiber can lead to a maximum increase in compressive strength and splitting tensile strength of approximately 7%, with 7-day strength achieving 55% to 64% of the 28-day strength. [1] The review evaluates methodological approaches across 20+ peer-reviewed studies, identifies critical fiber dosage thresholds (typically 0.2–0.5% by volume), and discusses the microstructural mechanisms underlying strength enhancement. Basalt fiber cement-based composites demonstrate enhanced tensile strength, impact resistance, and durability, reducing cracking sensitivity and extending service life, particularly in extreme environments such as bridges, tunnels, high-rise buildings, and ocean engineering. [1] Research gaps regarding long-term durability under coupled environmental stresses and predictive modeling of early-age strength development remain significant areas for future investigation.
