Abstract
Concrete is one of the most utilized construction materials because of its excellent compressive strength and durability. Nevertheless, its relatively low tensile and flexural capacities often limit its performance in structures subjected to tensile stresses. To address this limitation, fiber reinforcement has emerged as an effective technique for enhancing the mechanical behavior of concrete. This study examines the influence of chopped basalt fibers on the strength characteristics of concrete through a series of laboratory investigations. Basalt fibers with lengths of 12 mm and 18 mm, representing different aspect ratios, were incorporated into concrete mixtures at volume fractions of 0.25%, 0.50%, and 1.00%. The prepared specimens were evaluated for compressive strength, split-tensile strength, and flexural strength. In addition, the performance of the fiber-reinforced concrete was assessed after exposure to elevated temperatures of 300°C and 500°C to determine its thermal resistance and residual strength characteristics. The experimental findings revealed that the inclusion of basalt fibers contributed positively to the mechanical performance of concrete. Improvements were observed in tensile and flexural behavior, while compressive strength also showed enhancement compared to conventional concrete mixes. Furthermore, the fiber-reinforced specimens demonstrated better resistance to strength degradation under high-temperature conditions. The results suggest that basalt fibers can serve as an effective reinforcing material for producing concrete with improved structural performance, crack resistance, and durability, making it suitable for applications where enhanced mechanical and thermal properties are required. The flexural and split-tensile strength increased with an increase in the aspect ratio of fibers, while compressive strength showed improvement up to 0.50% fiber dosage. The study also revealed that concrete remained nearly unaffected in appearance and strength up to 350°C. However, at 500°C, slight deterioration in concrete quality and reduction in strength were observed. The investigation concludes that basalt-fiber-reinforced concrete exhibits enhanced mechanical properties and better thermal resistance compared to conventional concrete.
