Comparative study of the impact of basalt and steel fibers on the mechanical properties of hardened concrete

Original language description

For their advantageous properties and availability, basalt products have become an emerging green high-tech industrial material that is used in various building- and civil engineering applications as an alternative to widely used traditional types of reinforcement. Nevertheless, compared to the glass-, carbon- or steel-based fibers in cement composites, the literature focused on basalt reinforcing elements has been far less numerous. This paper is focused on a comparison of the impact of basalt (BF) and steel fibers (SF) on the mechanical properties of hardened concrete after 16 hours for the verification of early-age strength, which is essential in precast production, and at 28 days of hydration as a standard request. Several mixtures were prepared, containing different dosages of fibers: It was found that when a similar amount of both types of fibers was used, BF provided approximately 9% higher compressive strength of studied samples after 28 days. Moreover, when 0.48 vol.% and 0.90% of BF and SF, respectively, were added to the mixtures, the samples with BF showed more promising compressive strength by 15.3%. Nevertheless, in terms of the residual tensile strength, the same samples with BF exhibited almost five times worse performance than those prepared with SF, which should be addressed in future research.
