Experimental data of strength, deformability, and crack resistance of 2,000×200×100 mm reinforced concrete and basalt-concrete beams are given. Longitudinal reinforcement consisted of 2 Ø14 A500C for reinforced concrete beams and 2 Ø14 BFRP (AKB800) for basalt-concrete beams. Transverse reinforcement consisted of 2 Ø3, 4, 5 ВрI for reinforced concrete beams and 2 Ø4, 6, 8 BFRP (АКБ800) for basalt-concrete beams. Beams were made of heavy concrete of C16/20, C30/35, and C40/50 classes. The experimental beam specimens were tested according to a four-point scheme as loosely supported beams loaded with two concentrated forces. Loading in the series of tests was stepwise increasing, static and low-cycle repeated at high levels of 0.50, 0.65, and 0.80F ult. Distance from supports to concentrated forces (shear span), a/h 0 , varied within 1, 2, 3. Experimental beam specimens were made and tested according to the theory of experimental design according to the Box B4, optimal plan D. Comparative analysis of main performance parameters of reinforced concrete and basalt-concrete beams under the action of abovementioned loads was performed. The necessity of these studies was determined by the unsatisfactory convergence of experimental and calculated values of bearing capacity of oblique sections of basalt-concrete beams determined according to existing standard methods. The studies have established the influence of design factors and loading nature on basic parameters of the working capacity of basalt-concrete beam elements in a form of experimental-statistical dependences. These results will form a basis for a physical model of resistance of oblique sections in such structures to external loads. The presented results will significantly supplement the existing database of the operation of beam basalt-concrete structures and will be used in the development of an analytical method for calculating strength, deformability, and crack resistance

“…The basalt fibers are non-toxic, natural, eco-friendly, and environmentally safe [33][34]. Characterized by their relatively low price, superior modulus, high strength, excellent stability, and resistance to chemical erosion and high temperatures [34][35], basalt fibers possess higher material properties (such as tensile strength and elastic modulus) than glass fibers and are far cheaper than carbon fibers [36][37][38][39]. Therefore, basalt FRP (BFRP) composites are considered as feasible and sustainable alternatives to conventional FRP composites for future strengthening applications of RC structures.…”

“…Basalt fibre reinforced polymers (BFRP) are advanced composite materials, and extensive research activity has been devoted to their production and possible applications in different fields of engineering, including civil engineering (Fiore et al [1]). The use of BFRP bars in concrete structural elements was investigated by Tharmarajah et al [2], Zhang et al [3], High et al [4], Elgabbas et al [5], Fan & Chang [6,7] and applied with self-compacting concrete (SCC) in Thompson's bridge in Northern Ireland (Taylor et al [8]). …”

Steel-free pre-stressed reinforced concrete may be used in aggressive environments to increase the durability of structural elements and to limit the carbon footprint by replacing steel with high-strength fibre composites. The design of a 10-m long steel-free precast fibre-reinforced concrete slab, pre-stressed with basalt-fibre reinforced polymer (BFRP) bars and shear-reinforced with glass-fibre reinforced polymer bars, is presented in this paper. Non-linear viscoelastic and elastic-plastic models have been employed for the prediction of the service and ultimate limit state flexural behaviour, respectively.Preliminary tests on the employed materials and a 3-point load test on the slab element are presented, together with indications on its manufacturing process. The proposed numerical analysis is validated against the experimental results.
