Crumb rubber concrete (CRC) offers an environmentally sustainable solution for recycling waste tires through their use as a partial replacement for natural aggregates. However, limited research has investigated the structural behavior of CRC beams reinforced with basalt fiber-reinforced polymer (BFRP) bars. This study experimentally evaluates the flexural performance of CRC beams reinforced with BFRP bars under four-point bending. Fifteen reinforced con- crete beams were tested to investigate the effects of crumb rubber (CR) replacement ratio (0%–20%), rubber particle size (5 mm and No. 20), rein- forcement type (steel and BFRP), and BFRP reinforcement ratio on cracking behavior, stiffness, load-carrying capacity, and failure mode. The results showed that increasing CR content reduced concrete density, compressive strength, flexural strength, cracking load, stiffness, and ultimate load, with the reduction becoming more pronounced when finer rubber particles were used. CRC beams exhibited more distributed cracking patterns and greater deforma- tion capacity than conventional concrete beams. Regardless of concrete type, BFRP-reinforced beams developed significantly higher ultimate loads than steel-reinforced beams due to the superior tensile strength of BFRP bars. Increasing the BFRP reinforcement ratio improved cracking resistance, post- cracking stiffness, and ultimate flexural capacity. Among the investigated mix- tures, CRC containing 5% replacement of 5 mm CR exhibited the most favor- able balance between sustainability and structural performance. Analytical predictions based on ACI 440.1R, CSA S806, AASHTO LRFD, Gb 50608, JSCE, SP295, and Eurocode-based formulations showed reasonable agreement with the experimental results. The findings demonstrate the feasibility of utilizing BFRP-reinforced CRC members as sustainable, lightweight, and corrosion- resistant structural elements for future infrastructure applications.
Recently, hybrid reinforcement by combining steel with fiber- reinforced polymer (FRP) bars has emerged as a new system in reinforced concrete (RC) constructions. This reinforcement system can effectively overcome the ductility and serviceability challenges of FRP-RC structures. A total of 11 full-scale bridge-deck slabs were constructed and tested. The test parameters were reinforce- ment type, ratio, arrangement, and slab thickness. Moreover, a comparison between the experimental and predicted deflections from design provisions was carried out to verify the efficiency of the models for hybrid RC sections. Based on test results, hybrid RC slabs exhibited ductility leading to an ample warning before failure rather than brittle shear failure observed for FRP-RC slabs. In addition, hybrid RC slabs displayed good stiffness, service- ability, and load-carrying capacity. Furthermore, test results give an average bond-dependent coefficient, kb, of 1.27, close to the 1.2 recommended by ACI CODE-440.11-22. In addition, some modifications were proposed to shear equations available in different design codes to be valid for hybrid RC members without shear reinforcement.
