Summary: In this study, the L-shaped needle-wire electrode was used to simulate the coupling direction of mechanical stress and electric field in GFRP composites. The effects of equivalent tension and compression load on the electrical tree degradation of GFRP were obtained. It was found that both tension and compression load aggravated the electrical tree degradation, and the combined action of high temperature and high pressure and external mechanical load accelerated the degradation process.

Summary: Small-scale plain concrete notched beams strengthened with carbon and glass fiber reinforced polymer (CFRP and GFRP) sheets were tested in flexure to assess the change in debond onset strain following sustained flexural loading in both indoor and outdoor environments for up to 13 years. The results showed that in indoor conditions, the debond onset strain of CFRP beams remained practically unchanged over the 13-year period, while a decrease was observed in the GFRP beams. On the other hand, outdoor conditions, including freeze-thaw cycles, rain, hot weather, and ultraviolet exposure, led to clear reductions in debond onset strain for both GFRP and CFRP strengthened beams.

Summary: The evaluation of frost resistance for concrete reinforced with FRP varies depending on the reinforcement methods used. In this study, freezing and thawing tests were conducted on FRP-reinforced concrete prisms and cylinders to simulate various structures in cold climates. The specimens' frost resistance was evaluated through reinforcement techniques, morphological analysis, weight tests, and relative dynamic modulus of elasticity tests. The findings showed significant differences in weight and strength changes after freeze-thaw cycles, with CFRP and GFRP-reinforced concrete exhibiting better resistance compared to unreinforced concrete. Finite element software ABAQUS was also used to simulate the freeze-thaw cycle test and verify the validity of the FRP-reinforced concrete model.

Summary: The acoustic emission (AE) characteristics of fibre-reinforced polymer (FRP)-reinforced concrete beams during fracture process were studied through three-point bending tests. The analysis of AE parameters showed that the crack initiation load and peak load of single-layer FRP-reinforced concrete beams initially increased and then decreased with increasing bonding length. The failure mode of multi-layer FRP-reinforced concrete beams resulted in a dangerous brittle failure known as "super-reinforcement failure". By combining load-time curves, AE ringing count-time curves, and AE energy-time curves, the time points of crack initiation load and instability load can be accurately determined. The damage state of FRP-reinforced concrete beams can be evaluated using the ratio of ringing count to duration (RA-AF) and the clearance factor index.

Summary: The effect of anchors on the flexural behavior of externally bonded FRP-reinforced concrete beams was studied through numerical simulation. It was found that the bonding behavior is closely related to the moment, regardless of the beam length. For beams with the same design moment, it is suggested to increase the anchor spacing while keeping the anchor width constant. A design methodology considering different failure modes is proposed and verified by test results.

Summary: The utilization of locally available marine resources for concrete preparation in reef or island areas can reduce construction time and costs of offshore projects. However, the properties of coral aggregates and the presence of chloride ions can affect the mechanical properties and durability of seawater coral aggregate concrete (CAC) structures reinforced with fiber-reinforced polymer (FRP) composites. This paper reviews the physical and mechanical characteristics of coral aggregates, the properties of CAC, the bond performance and durability of FRP bars in CAC, and the behavior of FRP-reinforced CAC structures.

Summary: This study proposed a homogeneity improvement approach to address the contradiction of light weight and high strength in concrete. The blending of high homogenous matrix-UHPC and the LWA with reduced particle size achieved theoretical homogenous structures, compensating for strength loss caused by LWA and confirming the feasibility of homogenous structure fabrication. Peridynamic modelling revealed that the high homogeneity altered crack propagation, facilitated ductile failure mode formation, and improved strength, providing ideas for the application of ultra-low strength LWA in developing ultra-high strength LWC.

Summary: This study investigated the transport behavior of water and ions in the CSH nanocone pores using molecular dynamics. The results showed that the migration rate of ions is slower than water due to the adsorption of ions on the CSH substrate, the formation of ion clusters, and the blocking of CSH nanocone tips. Additionally, the inclination angles of the CSH substrate also affect the transport behavior.

Summary: Graphene sheet (GS) and graphene oxide (GO) can effectively suppress ice crystallization and inhibit icing on calcium silicate hydrate (CSH) surfaces. The inhibition of icing is attributed to the disruption of the crystallization process by massive H-bonds between CSH and GO. Additionally, freezing of the solution leads to the migration of salt ions to the surface of GO sheets and the formation of weak limited water (WLW). This study provides insights into the anti-freezing ability of cement-based materials using GS/GO additives.

This study investigated the nanoscale process of gamma-FeOOH deterioration using reactive molecular dynamics and electronic structures, revealing that defects facilitate chloride attack by weakening the structure of gamma-FeOOH. The Cl- ions adsorb on the defects, leading to the formation of Cl-Na pairs and the subsequent vibration-induced deterioration of the gamma-FeOOH structure.

Summary: This study aimed to improve the carbonation efficiency and reduce processing time of recycled concrete aggregates (RCAs). Wet carbonation with seawater was found to be more efficient than dry carbonation, leading to significant reduction in water absorption and increase in density of RCAs. The compressive strength of recycled aggregate concrete (RAC) prepared with 1-hour seawater carbonated RCAs was also improved. The formation of ettringite and calcite under wet carbonation contributed to the increased density and strength, as well as improved bond strength in the interfacial transition zone of RAC. Seawater presents several advantages as a medium for wet carbonation, including its abundant availability, CO2 capture capacity, and accelerated hydration and carbonation.
