“…All BCC beams showed excellent behavior and the 200 mm long notch connection exhibited higher bearing capacity. With the development of various engineering materials (Ding et al, 2018;Zhang et al, 2018), fiber reinforced polymer had been widely used in the reinforcement of structural members (Wei et al, 2017a;Ding et al, 2019;Zhang et al, 2020). Wei et al (2014) presented a new fiber reinforced polymer-bamboo-concrete composite structure.…”

To investigate the similarities and differences of mechanical behavior between the bamboo-concrete connections and the wood-concrete connections, thirty-six specimens were tested through push-out tests with the material type (bamboo or wood), concrete strength and dowel diameter as test parameters. In addition to the linear variable displacement transducer the digital image correlation was also used to obtain the slip distribution of the whole field of the specimens, which was conducive to the further detailed analysis of the slip distribution and a comprehensive understanding of the load-slip relationship. The results showed that the failure modes of the bamboo-concrete connections were similar to that of the wood-concrete connections, such as the concrete failure near the joint and the dowels bending in different degrees. The load-slip curves of the two kinds of connections were similar, which could be summarized as the elastic section, strengthening section and descending section. The shear stiffness and capacity of bamboo-concrete connections were higher than that of wood-concrete connections, and the shear capacity increased with the increase of dowel diameter and concrete strength. The slip distribution of the left and right sides of the specimen was basically identical. The load-transfer performance of the dowel was excellent. Finally, the prediction method of shear capacity and load-slip curve model of composite connections were proposed and verified to be effective.

“…Besides, the coral aggregates generally have sufficient bond performance with the surrounding paste and the interfacial transition zones are hardly detected [15,16]. Thus, the fracture of coral aggregates is a common failure mode in CAC [17]. Lyu et al [18] analyzed the effects of sphericity, angular number and index, shape, and texture of coral particles on the properties of CAC.…”

“…Moreover, because both the seawater and coral aggregates may have high saline content, steel bar cannot be effectively used in reinforced CAC structures. Fiber-reinforced polymer (FRP), as a non-metallic material, can be used instead of steel in CAC structures [13,17,21,22], due to its high resistance to chloride corrosion. Yang et al [13] analyzed the bond behavior between CAC and FRP bars with different FRP types, diameters, surface types, bond lengths, and curing conditions.…”

“…Yang et al [13] analyzed the bond behavior between CAC and FRP bars with different FRP types, diameters, surface types, bond lengths, and curing conditions. Basalt FRP (BFRP) bars have good durability in CAC that is immersed in saline solution [17]. However, Wang et al [21] found that the bond strength is reduced under the condition of seawater immersion with high temperature.…”

The intention of this paper is to analyze the properties of coral aggregate concrete (CAC) that is reinforced by alkali-resistant glass fibers (ARGF) and the bond performance with BFRP (basalt fiber reinforced polymer) bars. Two types of ARGF, denoted by Type A and Type B with different manufacturing technologies and fiber lengths, are used in the test. Tests of compressive strength, splitting tensile strength, and flexural performance were performed on ARGF-CAC with four different contents for the two types of ARGF. It is found that the cubic compressive strength is slightly reduced when the fiber volume fraction exceeds 0.5%, but almost keeps invariable if the fiber content further increases. However, the tensile strength, residual strength retention and flexural toughness are improved as more ARGFs are added into CAC, and even higher with Type B ARGF addition. The optimized volume fraction is 1.5% for both the two types of ARGF based on the evaluation of the workability and mechanical performance. Moreover, central pull-out test was performed to study the bond properties of ARGF-CAC with BFRP bars. It is found that both the maximum average bond stress and residual frictional stress are generally reduced as the bond length is longer. The addition of Type B ARGFs can significantly improve the bond strength; however, the Type A ARGFs seem to have marginal effect.

“…However, other studies 30–32 had demonstrated that in real‐field conditions, the GFRP durability is not affected in the alkaline environment of concrete and that did not cause any mechanical properties degradation. Another type of FRP rebar which is the basalt one are performed also by their resistivity to the alkaline and saline environments 33,34 . Recently, Salah‐Eddine et al 35 developed an analytical study to predict the axial‐ and flexural‐load capacity of the GFRP‐reinforced HSC.…”

This study has been undertaken for the assessment of steel/glass fiber reinforced polymer (GFRP) reinforced concrete mechanical behavior at an early stage. We developed a numerical model to describe the hydration process by using a chemo‐thermo‐mechanical scheme in ABAQUS finite element software. Mechanical properties of early age concrete versus hydration degree were determined using De Shutter's laws. The thermal and the autogenous strains are numerically implanted. Mazars elastic model was used to describe the concrete cracking. In addition, experimental validation of the established numerical model was performed and compared to the available literature. These data are selected for both plain and steel reinforced early age high‐strength concrete (HSC). Moreover, two mechanical boundary conditions were taken into account in accordance with the numerical simulations. Thermal conditions were considered in isothermal (20°C) and semiadiabatic conditions. Steel rebars were substituted by the GFRP under the same reinforcement percentages and configurations. The Interface between the steel and the GFRP reinforcement, and HSC was considered a perfect surface condition. Numerical predictions of the GFRP reinforcement were compared to those of steel reinforcement. Our results prove that the GFRP rebars restrain the concrete strains more than steel rebars. The GFRP rebar postpones concrete cracking compared to steel reinforcements. Furthermore, the concrete stress in the GFRP reinforced element is lower than the concrete stress in the RC steel.
