Abstract ：
A new nanocomposite g-C3N4/CoAl-LDH was synthesized and implemented to make alkali-activated steel slagbased photocatalytic pervious concrete (ASSPPC). The water permeability, compressive strength, microstructure, and NOx degradation ability of ASSPPC were investigated. The results show that at lower dosages (1 wt% and 3 wt%), the spherical structure facilitates excellent dispersion of g-C3N4/CoAl-LDH within the matrix, which leads to reduced matrix porosity, resulting in improved compressive strength and reduced water permeability in ASSPPC. Compared to control previous concrete, the compressive strength of ASSPPC with 1 wt% g-C3N4/CoAl- LDH increased by 6.3%, and water permeability of which decreased by 15.4%, respectively. However, at higher dosages (5 wt%), g-C3N4/CoAl-LDH tends to agglomerate, causing lower hydration degree and higher matrix porosity. Moreover, owing to the remarkable alkali resistance of g-C3N4/CoAl-LDH, ASSPPC with this photocatalyst only marginally decreases its NOx degradation ability as the curing age increases. When considering water permeability, compressive strength, and NOx degradation ability, ASSPPC with 3 wt% g-C3N4/CoAl-LDH demonstrates optimal performance, which gives both compressive strength and water permeability equivalent to pervious concrete without photocatalyst while exhibiting a NOx degradation rate 0.58 times higher than that of ASSPPC with 3 wt% g-C3N4.

Abstract ：
In this work, steel slag (SS), blast furnace slag (BFS), ultrafine SS (USS) and ultrafine BFS (UBFS), with fineness of 407, 450, 748 and 760 m2/kg respectively, were prepared. The influences of SS and BFS fineness on cementitious systems were studied from perspectives of the hydration process, microstructure formation as well as fluidity and strength. The results show that the BFS with a high fineness exhibits a high reactivity while an adverse effect on the fluidity. A high fineness of SS could have a negative impact on the hydration of blended cement. The addition of BFS, regardless of the fineness, substantially increases the number of small pores below 20 nm and enhances the compressive strength of cementitious systems. The combination of SS and BFS can decrease the Ca/Si ratio and raise the Al/Si ratio of the main hydrates C(-A)-S-H, while the fineness does not have a great impact on the chemical composition of C(-A)-S-H. Compared to plain cement, the gap-graded ternary cement prepared with 25 wt% cement, 39 wt% SS and 36 wt % UBFS is featured with a lower embodied energy and CO2 emission without compromising the early and late performances.

Abstract ：
Plug-pin joints are designed for easy assembly and fast construction. Full-scale experiments were carried out on three exterior beams-to-column joints subjected to reversal cyclic loading. It has been proved from experimental results that the proposed connection not only guarantees structural integrity but also moves the plastic hinge away from the column edge. Based on the experimental results, a novel plug-pin connection with integrated mild steel dampers is proposed. The energy dissipation joint fully adopts a dry connection method, and the joint's ductility is significantly improved by the integrated energy-dissipating steel plates. Finite element models are established to study the effects of different diameters of steel bars and thicknesses of energydissipating steel plates on structural response and mechanical properties under low cyclic reciprocating loads. Parameter studies were carried out, and the obtained results indicate that the proposed joints can bear a greater displacement load than that of cast-in-place joints and achieve greater energy dissipation. The maximum bearing capacity of the joint can be improved by increasing the thickness of the energy-dissipating steel plates, but the bearing capacity decline period of the joint will appear in advance under the same order of loading. If designed properly, structures installed with the plug-pin joint will be expected to adjust the order of plastic hinge development, thus achieving better seismic performance.

Abstract ：
Alkali-activated steel slag-slag pervious concrete (ASSPC) was prepared by using steel slag-slag composite powder instead of Portland cement and steel slag aggregate instead of natural aggregate. The compressive strength of ASSPC under different factors was studied, and the microscopic properties of hardened cementitious materials and interfacial transition zone (ITZ) of ASSPC were characterized by XRD, TG, FESEM and SEM-EDS. The effects of cementitious materials on the development of mechanical properties of ASSPC and its influence mechanism were clarified. The results show that ASSPC has high early compressive strength. With the increase of steel slag-slag ratio, the compressive strength increases first and then decreases. Using steel slag as aggregate to prepare pervious concrete effectively optimizes the microscopic properties of ITZ and improves the mechanical properties of ASSPC. With the increase of water-binder ratio (0.24～0.32), the compressive strength of ASSPC increases first and then decreases. © 2023 Bulletin of the Chinese Ceramic Society. All rights reserved.

Abstract ：
The utilization of steel slag (SS) in the field of concrete remains limited due to its poor soundness. This work studies the long-term volume stability and strength development (up to 1 year) of engineered cementitious composites (ECC) containing high-volume SS. The result shows that the compressive, splitting-tensile and flexural strength of ECC containing SS begins to decline after 90 d, while the decline in the corresponding matrix is much higher. Especially, the matrix with 60 wt% SS loses its integrity by 360 d. The expansion of SS reduces the fracture toughness of the matrix, leading to an increase in toughness and ductility, while changing the cracking pattern of the ECC. Additionally, the introduction of ground granulated blast furnace slag (GGBFS) results in a decrease in volume expansion and strength loss of ECC caused by expansion of SS. Randomly distributed PVA fibers restrict volume expansion of ECC containing SS, while trapped air pores introduced with PVA fibers act as relievers, dispersing expansive stress. Combined introduction of GGBFS and PVA fibers leads to a 49.8 % reduction in expansive strain and a 126 % increase in compressive strength of ECC compared with the matrix with high-volume SS.
