Abstract ：
为了研究激发剂种类对脱硫石膏-碱矿渣隧道防火涂料(DGAC)性能的影响机理,固定碱掺量为4％,碱矿渣水泥掺量为20％,探究激发剂种类,即CaO+Na2CO3、Ca(OH)2+Na2CO3、CaO+Na2SO4、Ca(OH)2+Na2SO4、NaOH,其所对应的 DGAC 分别为 CNC、CHNC、CNS、CHNS、NH,对 DGAC 干燥时间、凝结时间、干密度、抗压强度、耐水性及防火性的影响,并结合扫描电子显微镜(SEM)和X射线衍射(XRD)揭示其机理.结果表明:在干燥和凝结时间方面,CNS＞CHNS＞CNC＞CHNC＞NH;在抗压强度和耐水性方面,CHNC＞CNC＞NH＞CNS＞CHNS,CHNC生成的絮状水化硅酸钙(C-S-H)凝胶较多,其与针状钙矾石交叉紧密,具有最好的耐水性和抗压强度;在防火性方面,CHNS＞CNS＞NH＞CHNC＞CNC,CHNS和CNS中的激发剂碱性较低,其生成的C-S-H凝胶数量较少,且钙矾石的形态较粗,水化产物整体结构疏松,因此其抗压强度较低,但防火性较好.

Abstract ：
为研究配箍率对钢筋混凝土梁开裂特征的影响,依据我国规范设计了不同配箍率的钢筋混凝土梁,利用数字图像相关技术监测了钢筋混凝土梁试件在四点弯曲试验全过程,重现了不同级别荷载作用下试件的裂缝宽度及变形大小,并将试验结果与我国规范公式的计算结果进行对比.结果表明:数字图像相关技术能对全尺寸钢筋混凝土结构的裂缝及变形进行准确监测,钢筋混凝土梁在带裂缝工作阶段的裂缝宽度、间距均大于我国规范计算值,规范计算的裂缝宽度及间距均趋于保守,但我国规范可以对钢筋混凝土梁在带裂缝工作阶段的变形可以进行较好的预测.钢筋混凝土梁剪跨段裂缝分布及宽度受配箍率影响较大,纯弯段裂缝及宽度基本分布均匀,符合我国规范中裂缝计算公式的建立依据.

Abstract ：
在超高性能混凝土(UHPC)中采用饱和面干再生细骨料(RFA),不仅可减少UHPC收缩,还能节约成本.研究了相同净水胶比下饱和面干RFA掺量(0、50％和100％)对UHPC的电通量、抗压强度和碳化深度的影响,并通过分析UHPC的水化产物和孔结构揭示其机理.研究表明:随着饱和面干RFA掺量的增大,总水胶比增大,UHPC孔结构劣化,密实度降低,抗压强度降低,碳化深度增大.然而在相同碳化条件下,饱和面干RFA掺量为100％时,UHPC的碳化深度仍分别是普通混凝土和高性能混凝土的1/37.83～1/65.61和1/11.20～1/19.92.提出并验证了掺饱和面干RFA的UHPC碳化深度模型,为再生骨料UHPC推广及应用提供依据.

Abstract ：
The Interface Agent for Old Wall Tiles (IAWT) is an environmentally friendly material. However, its application in engineering is limited by its tendency to lose adhesion under harsh conditions. Factors such as freeze-thaw cycles, wind vibrations, rainfall, and thermal stress negatively affect the bond strength of IAWT. This study investigated the effects of PTB emulsion on various properties of IAWT, including bond strength, freeze-thaw resistance, wind vibration resistance, compressive-flexural ratio, water absorption, and microstructure. Orthogonal experiments were conducted to examine the impact of three key factors on the macroscopic properties of IAWT. The results indicated that increasing the ratio of PTB emulsion to water (P/W) improved bond strength under normal environmental conditions and enhanced freeze-thaw and wind vibration resistance. Furthermore, a higher P/W ratio reduced both the compressive-flexural ratio and water absorption. The addition of PTB emulsion slowed the hydration reaction, increased the number of micropores, and reduced the cumulative pore volume. Furthermore, it enhances the bond strength between the coating and the base layer, thereby increasing the durability of the renovation project for old walls. These enhancements yield positive economic and environmental benefits.

Abstract ：
This study reported the preparation of a visible-light-responsive polymer carbon nitride carbonized coating (VLPCNC) using gamma-C2S and photo-responsive polymer carbon nitride (PCN), primarily designed for air purification. The effects of varying PCN content on the photocatalytic properties, bonding strength, and erosion resistance of VLPCNC were investigated, with the mechanism analyzed through a series of microscopic techniques. Results demonstrated that VLPCNC with PCN displayed excellent photocatalytic efficiency under visible light. A rise in PCN content from 10 % to 50 % led to a substantial enhancement in the NO removal rate, increasing from 287.5 mu mol center dot m-2 center dot h-1 (14.7 %) to 720.9 mu mol center dot m-2 center dot h-1 (44.1 %). Incorporating 10 % of PCN could improve the bond strength of VLPCNC with concrete substrate. PCN could act as nucleation sites that enhance the carbonation of gamma-C2S, thus improving the bonding. However, a high PCN content significantly weakened the bond, as the dilution effect lowered the concentration of carbonation products in the binder. The NO removal performance of VLPCNC with 10 % PCN only reduced by 5.8 % after 1 d scouring treatment and the reduction increased when PCN content increased. All of the VLPCNC could remain good photocatalytic properties after 7 d scouring. The PCN particles were partially encapsulated by calcium carbonate crystals and adhered to their surface, enhancing the anti-scouring performance of VLPCNC. Notably, VLPCNC-10 exhibited a balance of exceptional photocatalytic properties, mechanical strength, and durability.

Abstract ：
Photocatalysis technology holds great potential in converting CO2 into value-added chemicals and fuels, playing a significant role in achieving carbon neutrality and promoting carbon cycling. However, the low charge carrier separation efficiency of existing photocatalysts limits their performance in CO2 utilization. Herein, a novel Sscheme structured 2D/2D WO3/InVO4 composite is successfully synthesized via hydrothermal method, which maintains the high selectivity for converting CO2 to CO under visible light without the need for noble metal cocatalysts or sacrificial agents. The optimized WO3/InVO4 composite exhibits CO yields of 13.37 mu mol/g, which is 3.36 times higher than that of InVO4. Enhancement in photocatalytic performance is primarily attributed to the meticulously designed S-scheme heterojunction structure, which effectively achieves spatial separation of photogenerated charges. Furthermore, the intimate contact between 2D WO3 and 2D InVO4 enhances charge transfer efficiency. This work offers valuable insights for the design and construction of novel S-scheme heterojunction photocatalysts.

Abstract ：
Concrete dams are often subjected to complex loading conditions throughout their operational lifespan. This study investigates the fracture behavior of full-graded dam concrete (FGDC) under the combined action of cyclic and static loads, utilizing discontinuous cyclic fracture tests (DCFTs). With respect to static load, loading intervals with different duration and force are considered. Moreover, the acoustic emission (AE) technique is employed to monitor the fracture process in real time. The experimental results reveal a three-stage characteristic in the evolution of the maximum crack mouth opening displacement (CMOD) for both continuous cyclic fracture tests (CCFTs) and DCFTs. Furthermore, the total number of cyclic circles in DCFTs is smaller than that of CCFTs. The AE technique effectively characterizes the fracture process, and the cracking behavior is analyzed based on the rise angle (RA), average frequency (AF), AE amplitude, and location. The b value, calculated as the slope of the frequency-magnitude log-line, is also utilized to analyze the cracking behavior. The variations in b value reflect the information from the initiation of microcracks to the formation of macrofractures. The crack types are successfully classified using unsupervised machine learning methods of the Gaussian mixture model (GMM), and the self-organizing map (SOM). Finally, the width of the fracture process zone is determined, and a larger value of width in DCFTs is found.

Abstract ：
The existing fireproof coating on thick steel structures has many drawbacks, including its lack of environmental protection, susceptibility to detachment, prolonged drying duration, and intricate building procedures. In this study, magnesium potassium phosphate cement (MKPC) was selected for the development of inorganic fireproofing coatings, considering that it has better adhesion, fast hardening speed, and heat resistance compared to other cement-based materials. P/M (the mass ratio of dipotassium hydrogen phosphate to magnesium oxide) is the most important factor affecting the performance of MKPC, which indicates the ratio of the acid and base components of the system. When P/M changed, so did the content of hydration products (MKP). The experimental results demonstrate a direct correlation between the quantity of MKP and the performance of the coating. Consequently, the bonding and fire resistance mechanisms of MKPC coatings were investigated by studying the effect patterns of different P/M on the properties (bond strength, fire resistance limit, dry density, compressive strength) of MKPC fireproofing coatings in combination with microscopic tests such as SEM, TG-DSC, and MIP.

Abstract ：
Mimicking photosynthesis to convert CO2 and H2O into value-added chemicals represents an optimal approach to mitigate energy shortages and environmental pollution, and the development of highly efficient and selective photocatalysts for CO2 to CO conversion is essential for the effective utilization of CO2 resources. Herein, a novel 2D@0D InVO4@MnWO4 S-scheme heterojunction composite is successfully developed via an in situ hydrothermal method, achieving the conversion of CO2 into CO under visible light irradiation using H2O as a reducing agent, without any noble metal cocatalysts or sacrificial reagents. The CO generation rate over the optimal InVO4@MnWO4 composite reaches 6.20 mu mol g-1 h-1, which is approximately 4.50 times than that of InVO4. The enhanced photocatalytic performance is ascribed to the charge separation facilitated by the formation of an S-scheme heterojunction between InVO4 and MnWO4. This work is expected to provide a new insight for the design of highly selective photocatalysts for the conversion of CO2 to CO.
