Summary: Polyvinyl alcohol-graphene oxide-oxidized carbon nanotube hybrid coatings were used to modify glass fibers and carbon fibers, resulting in modified hybrid composites with different concentric structures. The hybrid structure optimized the mechanical properties of the composites by combining the advantages of the two types of fiber reinforcement, with interface strength playing a crucial role. Mechanical properties were significantly enhanced after modification, and interlaminar shear strength was improved with hybrid coating.

Summary: Acoustic emission (AE) is used for structural health assessment of materials, with potential applications in cementitious composites and polymers. However, factors such as wave propagation distance, plate geometry, heterogeneity, and reflections can lead to attenuation and distortion of AE waveforms, making interpretation more complex. This study investigates the effect of wave propagation on plain glass textile-reinforced cement (TRC) plates and evaluates how plate dimensions and propagation distance impact AE characteristics.

Summary: The seismic performance of the Hybrid steel-polyvinyl alcohol (PVA) Fiber Cement-based composite (HFC) encased concrete-filled steel tube (CFST) column was studied through cyclic loading tests on six specimens. The influence of core concrete strength, steel tube thickness, and axial compression ratio on seismic performance was analyzed. The results showed that increasing core concrete strength improved capacity and energy dissipation but decreased ductility. HFC-encased CFST columns with lower axial compression ratio and thicker steel tubes exhibited better seismic performance. Theoretical capacity evaluation models, based on superposition method and reasonable assumptions, were proposed and showed high accuracy when compared with experimental results. Finite element models demonstrated that increasing PVA fiber ratio and steel tube strength grade significantly improved seismic performance of composite columns.

Summary: This paper evaluates the physical and chemical properties of mortar mixtures with different binders and exposed to different sulphate solutions. A theoretical approach to describe the susceptibility of cementitious mixtures against sulphate attack is proposed. The results show that the amount of portlandite and the potential of ettringite formation are well correlated with the expansion and damage caused by sulphate attack.

Summary: Concrete cracks in marine engineering are caused by the hostile seawater environment, leading to serious deterioration of infrastructures. Microbial induced carbonate precipitation (MICP) is an effective and environmentally friendly approach for self-healing of concrete cracks. However, the formation and structure of MICP products for crack healing in seawater are still unclear, which hinders the application of MICP in marine structures.

Summary: This study investigates the potential use of engineered cementitious composites (ECCs) with strain-hardening and self-healing characteristics as a cover material in wet coral sand exposure. The results show that ECCs can effectively close cracks, reduce water permeability, and restore the load-carrying capacity of structures. Additionally, lower strain levels are associated with decreased rebar corrosion.

Summary: This study investigates the long-term volume stability and strength development of engineered cementitious composites (ECC) containing high-volume steel slag (SS). It is found that the strength of ECC with SS starts to decline after 90 days, while the decline is more significant compared to the matrix. The expansion of SS reduces the fracture toughness of the matrix, leading to an increase in toughness and ductility of the ECC. The introduction of ground granulated blast furnace slag (GGBFS) and PVA fibers can reduce the volume expansion and strength loss caused by SS expansion.

Summary: This study investigated the leaching rate of Ca2+ from magnesium slag (MS) and developed a leaching-carbonation method to convert MS into high-purity vaterite and supplementary cementitious materials. The wet carbonation process with glycine as a crystal modifier successfully produced spherical vaterite with high purity and surface area. The leachate solid residue (LSR) obtained from the leaching process of MS showed a smaller size destruction and higher surface area compared to Portland cement, leading to accelerated hydration process and improved compressive strength and pore structure development. This work provides a novel treatment method for MS and enables its high value-added utilization.

Summary: The effects of DEIPA and EDIPA at dosages of 0.02% and 0.05% on the hydration and strength development of cement-fly ash-limestone ternary blend were investigated. It was found that both dosages of DEIPA and EDIPA promote the chemical effect of limestone and the hydration of aluminates from cement and fly ash. The hydration of silicates was accelerated by 0.02% of DEIPA or EDIPA but delayed by 0.05% due to excessive aluminates hydration. DEIPA and EDIPA also refine the pore structure and increase compressive strength of the blend mortar.

Summary: This study explores a method of strengthening cemented rockfill by using well-graded gangue and partially replacing Portland cement with fly ash and a premixed low-alkalinity activator. The research investigated the effects of activator dosage and curing time on the mechanical properties, composition, and microstructure of cemented rockfill. Results show improved performance with low cement content and the use of a low-cost activator. The addition of premixed activator to fly ash enhanced the formation of specific minerals and caused densification of the microstructure. The study reveals an effective and low-cost method for recycling mining wastes and reducing cement.

Summary: This study proposes a solution to improve the fresh stability and thermal insulation of alkali-activated foamed concrete by adding recycled brick powder. The study investigates the effects of activator modulus and Na2O concentration on the properties of alkali-activated foamed concrete with different bases. The presence of alkaline activator negatively affects the foamability and foam stability, but adjusting the activator concentration can achieve shorter initial setting time and higher fluidity loss. In addition, the increased activator concentration resulted in changes in the pore structure of the foamed concrete.

Summary: Nitrite ion intercalated Ca-Al and Mg-Al layered double hydroxides (LDHs) were successfully synthesized using two modified methods. The Ca-Al LDH synthesized by hydrothermal method (H-C-LDH) exhibited the best properties. The intercalated LDHs improved the mechanical properties, chloride penetration resistance, and permeability resistance of cement mortars without affecting the fluidity. Additionally, the intercalated LDHs provided better corrosion resistance.

Summary: This review paper provides an overview of internal curing mechanism, common internal curing agents, and the most promising agent-superabsorbent polymers in alkali-activated materials (AAM) systems. The introduction of voids by internal curing agents typically has a negative impact on mechanical properties, but continuous water release during internal curing counteracts this effect by promoting hydration. While the effect of internal curing in reducing autogenous shrinkage of AAM systems has been well-established, the impact on drying shrinkage varies widely in different studies.
