Summary: The objective of this study is to evaluate the effect of incorporating rice husk ash (RHA) into ground granulated blast furnace slag (GGBS) based alkali activated concrete (AAC) at ambient temperature. The hardened properties of AAC were evaluated through destructive and non-destructive tests, and the microstructural characteristics were analyzed using SEM and FTIR. The test results showed that the compressive strength of AAC reached its maximum at up to 10% RHA content. Beyond that, the strength decreased, but the AAC still had adequate strength for structural applications. The SEM test showed that a lower percentage of RHA resulted in a dense microstructure, while a higher percentage led to cracks and voids.

Summary: In this study, a numerical model was developed to investigate the effect of cyclic fluid pressure induced by waves on chloride transport behavior in concrete. The results showed that the concentration of free chloride in concrete is controlled by the concentration of C-S-H on the concrete pore surface and its binding affinity. Additionally, there is an optimal aggregate volume fraction that improves the durability of offshore RC structures. While aggregates limit chloride penetration, an increase in the interfacial transition zone of the concrete enhances the diffusion of chloride ions. Furthermore, cyclic fluid pressure increases the long-term uptake of chloride ions and accelerates the initiation of corrosion.

Summary: The purpose of this paper is to study the effects of a moveable guide vane with various configurations in controlling the vortex-induced vibration (VIV) of a long-span suspension bridge with twin-box girder. VIV tests were conducted on a 1:50 scaled model with different guide vane configurations. The results show that the moveable guide vane can significantly reduce the maximum displacement responses of the main girder, especially under unfavorable wind attack angles. The stiffness and length of the guide vane also affect the VIV control, with lower stiffness and shorter length leading to better outcomes. The leeward guide vane plays an important role in VIV suppression when its stiffness exceeds a certain threshold.

Summary: This paper proposes and validates a novel column strengthening technique incorporating section curvilinearization (SC) using ultra-high performance engineered cementitious composites (UHP-ECC) and fiber-reinforced polymer (FRP) confinement. Eleven large-scaled FRP-confined square reinforced concrete (RC) columns with SC using UHP-ECC as the additive material were prepared and tested. The main parameters investigated in this paper included the FRP thickness, the rise-to-span ratio, and the strength of the additive concrete. Test results show that the SC technique with FRP jacketing and UHP-ECC as the additive material enhances the load-bearing capacity of the RC columns by 52% with a 17% section increment. By assessing the existing design-oriented stress-strain models of confined concrete in curvilinearized square columns (CSCs) using the test results obtained in this study, it reveals that the current models could underestimate the ultimate strength of the confined concrete in CSCs with a two-layer FRP wrap, and therefore further research on the improvement on the stress-strain model of confined concrete in CSCs becomes necessary.

Summary: A novel graphene oxide/belite cement (GO/BC) composite was synthesized and applied to OPC-based mortar specimens to address the size mismatch between nanoscale graphene oxide and micron-scale ordinary portland cement (OPC). The morphology, surface area, and pore size distributions of the hydrated GO/BC composites were characterized. The composite showed improved flexural strength and densification of the ITZ region compared to graphene oxide or belite cement alone, suggesting that hydrated GO/BC composites could serve as a better nucleation seed for promoting OPC hydration due to their greater surface area, suitable sizes, and chemical interactions with belite cement.

Summary: Due to the complexity of broken rock mass structure with discontinuity and anisotropy, grouting reinforcement is generally necessary in underground construction. This study experimentally investigates the mechanical properties of grouted broken rock mass, considering characteristics such as degree of fragmentation and shape, as well as reinforcement methods such as relative strength ratio and volumetric block proportion. The results show that strength and deformation of the reinforced rock mass depend on relative strength ratio and volumetric block proportion. Additionally, the shape of the rock mass has a significant influence on compressive strength enhancement, especially under high strength ratios.

The results indicate that despite the free cooling operation by the indirect evaporative cooler, the proposed system consumes 10% more operating energy due to the low coefficient of performance (COP) of the isothermal dehumidifier. Improvements in the COP of the isothermal dehumidifier are required for comparable energy performance.

Summary: This study investigates the property-microstructure relationships in graphene nanoplatelet (GNP) reinforced cement composites (GNPRCCs) using three-dimensional finite element modeling and experiments. The results reveal that GNPs aligned at 45 degrees have the most significant impact on enhancing load-bearing capacity and damage resistance of the composites. A larger GNP diameter-to-thickness ratio is beneficial for crack bridging and propagation control. The orientation and porosity of pores have significant effects on the damage behaviors of the composites, while pore shape shows negligible effects. These findings provide key guidelines for optimizing microstructural features and improving the performance and durability of construction materials.
