The ultimate shear strength of ECC is high more elevated than conventional concrete when using 70 % of GGBS [7]. The use of industrial waste, specifically GGBS as cement replacement in ECC mixture, increases the strength and improves fiber bridging property that results in better ductility of the ECC [8].…”

During the last decade, concrete technology has been undergoing rapid development, resulting in a new concept of engineered cementitious composite (ECC) to overcome the brittle behaviour of cement-based materials. ECC is one movement to fully incorporate waste material as an innovation in green material due to excellent toughness and energy absorption capacity, self-healing ability, fire performance, and remain durable under erosion environment. ECC exhibits a strain-hardening behaviour through the formation of micro cracking. This study is focusing on the tensile behaviour of the slag-based ECC. A total of five ECC mixes were designed with different cement to ground granulated blast-furnace slag (GGBS) ratio. Five samples of dog bone and three cylindrical for each mixture were prepared for direct tensile and compression tests. Compared to control samples, there are increments in compressive strength for samples contained 50-60% of GGBS and reductions in compressive strength for samples contained 70-80% of GGBS. The tensile strengths of ECC increase in the rate proportionally to the content of GGBS in ECC mixtures. The failure modes of the ECC cylinder samples including crushing under compressive load and few micro cracks are observed in ECC dog bones.

“…The shear behavior of ECC elements is influenced by parameters such as (a) the diameter and spacing of transverse reinforcements, (b) shear span (a v ) to depth (h) ratio, (c) mode of failure and (d) size effect [ 17 , 18 ]. Several preceding works have investigated the ECC-based structural elements’ performance under shear loads [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Meng et al [ 19 ] examined the shear resistance of polyvinyl alcohol fiber-based ECC members with and without transverse reinforcements.…”

“…The previous studies show that the ECC members prepared using different fibers experienced failure due to the ductile flexure mode when loaded in shear [ 23 , 24 ]. Reviewing the existing literature studies, it is clear that only a handful of studies are available for understanding the shear behavior of ECC-based structural elements [ 25 , 26 , 27 ]. It is worth noting that the use of combined synthetic PVA and PP fibers on the shear behavior of ECC beams is not available.…”

The shear behavior of innovative engineered cementitious composites (ECC) members with a hybrid mix of polyvinyl alcohol (PVA) and polypropylene (PP) fibers is examined. The overall objective of the investigation is to understand the shear behavior of ECC beams with different mono and hybrid fiber combinations without compromising the strength and ductility. Four different configurations of beams were prepared and tested, including 2.0% of PP fibers, 2.0% of PVA fibers, 2.0% of steel fibers and hybrid PVA and PP fibers (i.e., 1% PP and 1% PVA). In addition to the tests, a detailed nonlinear finite element (FE) analysis was accomplished using the commercial ABAQUS software. The validated FE model was used to perform an extensive parametric investigation to optimize the design parameters for the hybrid-fiber-reinforced ECC beams under shear. The results revealed that the use of hybrid PVA and PP fibers improved the performance by enhancing the overall strength and ductility compared to the steel and PP-fiber-based ECC beams. Incorporating hybrid fibers into ECC beams increased the critical shear crack angle, indicating the transition of a failure from a brittle diagonal tension to a ductile bending.

“…Although there has been considerable research on the flexural response of FRP‐reinforced SHCC members, investigations regarding their shear behavior are rare. Since the shear behavior of reinforced structural member is greatly influenced by the tensile properties of matrix, FRP‐reinforced SHCC would exhibit quite different shear resisting mechanisms from that of concrete 17–30 . To investigate the shear behavior of FRP‐reinforced SHCC beams, a set of four‐point bending tests was conducted.…”

Application of fiber-reinforced polymer (FRP) reinforcement in concrete beams may cause large deflection and crack width, as well as low shear capacity and ductility due to relatively small stiffness of FRP materials. To avoid these unfavorable factors and evaluate the shear behavior of FRP-reinforced structural members, a high-performance strain-hardening cementitious composite (SHCC) is introduced to substitute conventional concrete in reinforced beams, and four-point bending test is conducted in this study. Six FRP-reinforced SHCC beams with different transverse reinforcement ratios and shear spans, as well as one concrete reference beam, were tested. According to the test results, the FRP-reinforced SHCC beam showed enhanced shear carrying capacity and superior ductility compared with the concrete beams. The shear span to effective depth ratio as well as the stirrup ratio has a great influence on the shear behavior of FRP-reinforced SHCC beams, including the failure mode, load-carrying capacity, crack propagation, and ductility. Finally, a simplified truss-strut model for predicting shear carrying capacity of steel or FRP-reinforced SHCC beams is proposed, and a good agreement is achieved with the experimental results.ductility, failure mode, fiber-reinforced polymer (FRP) reinforcement, shear strength, simplified truss-strut model, strain-hardening cementitious composite (SHCC)
