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

Popis výsledku v původním jazyce

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.
