Red mud and coal gangue powder were employed as substitutes for cement to prepare red mud concrete, coal gangue concrete, and red mud-coal gangue concrete. The effects of red mud and coal gangue powder on the physical properties, workability, and mechanical properties of concretes were evaluated, and the hydration reaction mechanisms were elucidated through microanalysis. Furthermore, the reaction process was investigated through thermogravimetric analysis. The results indicated that the individual addition of red mud and coal gangue powder had negative effect on the strength, workability, and porosity of concretes. However, the combination of red mud and coal gangue powder significantly improved the strength and porosity of the concrete compared to red mud concrete and coal gangue concrete. The red mud-coal gangue concrete with 15 % red mud and 15 % coal gangue powder had lower porosity, and comparable compressive strength with the cement concrete. The microscopic results and thermogravimetric analyses indicated that the synergistic effect of red mud and coal gangue led to the improvement of the strength of red mud-coal gangue concrete. The red mud exhibited the promotion effect on the hydration of coal gangue powder to generate new C-S-H, filling the pores. The denser structure in the red mud-coal gangue concrete was formed, thereby improving the pore space and mechanical properties of the concretes.

采用赤泥和煤矸石粉替代水泥制备了赤泥混凝土、煤矸石混凝土和赤泥-煤矸石混凝土。评价了赤泥和煤矸石粉对混凝土物理性能、工作性和力学性能的影响，并通过显微分析阐明了水化反应机理。此外，还通过热重分析研究了反应过程。结果表明，单独添加赤泥和煤矸石粉对混凝土的强度、工作性和孔隙率有负面影响。然而，与赤泥混凝土和煤矸石混凝土相比，赤泥和煤矸石粉的组合明显提高了混凝土的强度和孔隙率。含 15% 赤泥和 15% 煤矸石粉的赤泥-煤矸石混凝土孔隙率较低，抗压强度与水泥混凝土相当。微观结果和热重分析表明，赤泥和煤矸石的协同作用提高了赤泥-煤矸石混凝土的强度。赤泥对煤矸石粉的水化有促进作用，使其生成新的 C-S-H，填充孔隙。在赤泥-煤矸石混凝土中形成了更致密的结构，从而改善了混凝土的孔隙空间和力学性能。

Steel plate concrete shear walls (SC walls) have been widely used in practical projects because of great mechanical properties. For the application in nuclear power plant containment, the joint of specially shaped reinforced concrete slab and SC walls is difficult to design and construct. By using ultra-high performance concrete (UHPC), a new type of joint with the non-contact lapping method is proposed in this paper, which has advantages of simple construction, superior performance, suitable cost, and wide application range. Five RC-UHPC slab-shear wall joints were designed and tested under reciprocating load to study the effects of structures of lapping steel plate, shear-resisting methods, and interfacial reinforcing methods on the mechanical properties of the joints. The test results showed that the joints adopting the new structures were damaged for the flexural failure of the concrete area, with no damage to the joint zone, while the other specimens failed in the shear failure of the joint zone. It can be demonstrated that the ribs formed by bars and studs on the lapping steel plates are effective measures for non-contact force transferring, and interfacial reinforcing bars can improve the strength of the interface between concrete and UHPC. The force transferring efficiency of the new joints was close to or more than 90 %, which indicates that the proposed joint structures can effectively realize the non-contact lapping force transferring. The design formulas and suggestions are proposed based on the analysis of the mechanism of new structures.

钢板混凝土剪力墙（SC 墙）因其优异的力学性能而在实际工程中得到广泛应用。在核电站安全壳的应用中，特殊形状的钢筋混凝土板与钢板混凝土剪力墙的接缝设计和施工难度较大。本文利用超高性能混凝土（UHPC），提出了一种非接触搭接法的新型接缝，具有施工简单、性能优越、成本适宜、应用范围广等优点。本文设计了五种 RC-UHPC 板剪力墙接头，并在往复荷载作用下进行了试验，研究了碾压钢板结构、抗剪方法和界面加固方法对接头力学性能的影响。试验结果表明，采用新结构的接头在混凝土区域挠曲破坏，接头区无损伤，而其他试件则在接头区剪切破坏。由此可见，搭接钢板上由钢筋和螺柱形成的肋条是非接触传力的有效措施，而界面钢筋可提高混凝土与 UHPC 之间的界面强度。新型接头的传力效率接近或超过 90%，这表明所提出的接头结构能有效实现非接触碾压传力。在分析新型结构机理的基础上，提出了设计公式和建议。

The construction industry considerably contributes to global CO₂ emissions, primarily by preparing raw materials for cement production, which necessitates sustainable alternatives. Incorporating biowaste-based constituents into construction materials can help to reduce carbon footprint of the cement production. Various kinds of biowaste (organic and inorganic) can be converted to supplementary cementitious materials (SCMs). Organic waste (e.g., agricultural and forestry waste) are used as SCMs in the form of biochar and ash composed of carbon and mineral species like SiO₂ and CaO, made by thermochemical conversion process such as pyrolysis and combustion, respectively. Inorganic waste (e.g., eggshells and seashells) has compositions similar to ordinary cement (e.g., a high CaO content); thus, it can be employed as SCMs after grinding. The results thus far have reported that biowaste-derived SCMs can enhance the mechanical, physical, and environmental properties of the final product. Nevertheless, despite the positive aspects of using biowaste as SCMs, it may negatively affect cement reaction and structural performance. It is hoped that a balanced overview of the utilization of biowaste-derived SCMs provided in this review will foster more extensive research on environmentally friendlier construction materials.

建筑业主要通过准备水泥生产所需的原材料，大大增加了全球二氧化碳排放量，因此需要可持续的替代品。在建筑材料中加入生物废料成分有助于减少水泥生产的碳足迹。各种生物废弃物（有机和无机）都可转化为水泥基补充材料（SCMs）。有机废弃物（如农业和林业废弃物）通过热解和燃烧等热化学转化过程，以生物炭和灰烬的形式用作 SCM，生物炭和灰烬由碳和 SiO2 和 CaO 等矿物质组成。无机废物（如蛋壳和贝壳）的成分与普通水泥类似（如 CaO 含量较高），因此可在研磨后用作 SCM。迄今为止的研究结果表明，生物废弃物衍生的 SCM 可提高最终产品的机械、物理和环境性能。然而，尽管使用生物废料作为 SCMs 有其积极意义，但它可能会对水泥反应和结构性能产生负面影响。希望本综述对生物废料衍生 SCM 利用情况的均衡概述能促进对更环保的建筑材料进行更广泛的研究。

Selection and evaluation of commercial low-cost devices for indoor air quality monitoring in schools 选择和评估用于监测学校室内空气质量的低成本商用设备

IF 6.7 2区工程技术 Q1 CONSTRUCTION & BUILDING TECHNOLOGY

The use of low-cost sensors for monitoring Indoor Air Quality (IAQ) in schools has shown promising results, with the commercialisation of these devices increasing worldwide. This study aims to identify an effective, commercially available low-cost device for IAQ monitoring in schools.

Four low-cost devices (AirVisual Pro, PocketLab Air, PurpleAir PA-II-SD and uRAD Monitor A3) were selected for both qualitative and performance evaluations. Field tests were conducted in six indoor microenvironments within a nursery and a primary school. The low-cost devices were co-located with research-grade instruments to obtain reference concentrations of PM₁, PM_2.5, PM₁₀, CO₂, VOC, formaldehyde and O₃.

The qualitative evaluation revealed limitations, including data loss, negative or erratic values, inconsistent timestamps, and connectivity issues. PM low-cost devices exhibited better performance during non-occupancy periods but faced challenges during periods of occupancy. All devices tended to underestimate measurements compared to reference data, although AirVisual Pro performed better for PM_2.5 during occupancy. Furthermore, CO₂ concentrations were slightly overestimated, showing improved accuracy during occupancy periods. While formaldehyde peaks were detected by the low-cost device, overall performance was weak for both formaldehyde and O₃.

The results indicated that AirVisual Pro demonstrated the best overall performance, and presents itself as a promising tool for IAQ monitoring in schools. However, performance evaluations should be tailored to specific microenvironments and occupancy periods. Despite some acceptable performance results, real-context use of the selected low-cost device should be preceded by a proper calibration. Additionally, long-term performance evaluation should be considered in future studies.

使用低成本传感器监测学校室内空气质量（IAQ）已取得了可喜的成果，这些设备在全球范围内的商业化程度也在不断提高。本研究旨在为学校的室内空气质量监测确定一种有效的商用低成本设备。研究人员选择了四种低成本设备（AirVisual Pro、PocketLab Air、PurpleAir PA-II-SD 和 uRAD Monitor A3）进行质量和性能评估。在一所幼儿园和一所小学的六个室内微环境中进行了实地测试。定性评估发现了一些局限性，包括数据丢失、数值为负或不稳定、时间戳不一致以及连接问题。PM 低成本设备在非占用期表现较好，但在占用期面临挑战。与参考数据相比，所有设备都倾向于低估测量值，不过 AirVisual Pro 在占用期间的 PM2.5 测量值表现较好。此外，二氧化碳浓度被略微高估，但在占用期间的准确性有所提高。结果表明，AirVisual Pro 的整体性能最佳，是学校室内空气质量监测的理想工具。不过，性能评估应根据具体的微环境和占用时间进行。尽管取得了一些可以接受的性能结果，但在实际使用所选的低成本设备之前，应先进行适当的校准。此外，在今后的研究中还应考虑长期性能评估。

Uneven temperature distributions in the glass panes of building façades can induce thermal stresses exceeding material strength, a critical condition usually referred to as “thermal shock”. Here, we specialize in architectural glazing a recently-proposed flux-based variational approach to thermal problems, by considering heat exchanges resulting from climatic actions, in particular the variability of environmental temperatures and solar radiation, influenced by the shielding of cast shadows. The finite element implementation is facilitated because the unknown field is the heat displacement, whose time derivative is the heat flux, which is much smoother than the temperature field, on which the classical approach via Fourier’s law is based. A custom in-house-made FEM code is used to determine the effect of size and shape of cast shadows on temperature distribution in monolithic and laminated glass panes, also coupled in insulating glass units. We find that the temperature difference between irradiated and shadowed regions is only mildly influenced by the shape and size of the shadows, but the glass thickness determines the width of the transition zone and, hence, the temperature gradient. Practical rules for the design of glass façades are tentatively proposed.

建筑幕墙玻璃板中不均匀的温度分布会导致热应力超过材料强度，这种临界状态通常被称为 "热冲击"。在此，我们将最近提出的一种基于通量的热问题变分方法应用于建筑玻璃，该方法考虑了气候作用导致的热交换，特别是受投射阴影遮挡影响的环境温度和太阳辐射的变化。由于未知场是热位移，其时间导数是热通量，而热通量比温度场要平滑得多，因此便于有限元方法的实施。我们使用内部定制的有限元代码来确定投射阴影的大小和形状对整体玻璃板和夹层玻璃板（也包括中空玻璃单元）温度分布的影响。我们发现，照射区和阴影区之间的温差仅受阴影形状和大小的轻微影响，但玻璃厚度决定了过渡区的宽度，从而决定了温度梯度。我们初步提出了玻璃幕墙设计的实用规则。

The ambitious targets of carbon emission reduction set worldwide for the coming years entail the commitment of structural engineers towards the sustainable renovation of existing buildings. The life cycle thinking (LCT) approach offers a holistic perspective for the design of sustainable retrofitting strategies. It envisages the reduction of the environmental impact at all building life cycle phases, while also addressing economic and social issues. Multi-criteria decision-making (MCDM) approaches support the choice of optimal retrofitting solutions, thus being relevant tools for boosting the actual adoption of LCT in current practices. In this study, a previously proposed MCDM approach is enriched with additional LCT-inspired decision parameters (module D beyond-life impacts, environmental payback period, invasiveness), and is then scrutinised and discussed through its application to a case-study building. Four integrated retrofitting scenarios are investigated using state-of-art seismic loss and energy performance assessment methods, including four different types of exoskeletons, made of timber, steel, and concrete. The end-to-end integrated assessment shows that the inclusion of additional LCT-inspired decision criteria effectively favours LCT-based retrofitting interventions over more traditional ones.

未来几年，全世界都要实现宏伟的碳减排目标，这就要求结构工程师致力于对现有建筑进行可持续改造。生命周期思维（LCT）方法为可持续改造战略的设计提供了一个整体视角。它设想在建筑生命周期的各个阶段减少对环境的影响，同时解决经济和社会问题。多标准决策（MCDM）方法支持选择最佳改造方案，因此是促进在当前实践中实际采用 LCT 的相关工具。在本研究中，先前提出的 MCDM 方法增加了受 LCT 启发的决策参数（模块 D 的寿命期后影响、环境投资回收期、侵入性），并通过将其应用到案例研究建筑中进行了仔细研究和讨论。采用最先进的地震损失和能效评估方法，对四种综合改造方案进行了研究，包括四种不同类型的外骨骼（由木材、钢材和混凝土制成）。端到端综合评估结果表明，纳入额外的 LCT 启发决策标准后，基于 LCT 的改造干预措施比更传统的干预措施更有效。

The presented study provides an efficient and reliable tool for rapid shear capacity estimation of TRM-strengthened unreinforced masonry walls. For this purpose, a data-driven methodology based on a machine learning system is proposed using a dataset constituted of experimental results selected from the bibliography. The outlier points of the dataset were detected using the Cook’s distance methodology and removed from the raw dataset, which consisted of 113 examples and 11 input variables. In the processed dataset, 17 machine learning methods were trained, optimized through hyperparameter tuning, and compared on the test set. The most effective models were the optimized instances of XGBoost and CatBoost methods, which combined into a voting model to leverage the predictive capacity of more than a single regressor. The final blended model shows remarkable predicting capacity with the determination factor (

R^{2}

) equal to 0.95 and the mean absolute percentage error equal to 8.03%. Also, the model’s predictions are compared with those of existing analytical relationships, and it is found to perform the best of all. In sequence, machine learning interpretation methods are applied to find how the predictors influence the target output.

A_{m}

,

f_{t}

, and

n \cdot t_{f}

本研究为快速估算 TRM 加固非加固砌体墙的抗剪承载力提供了一个高效可靠的工具。为此，我们提出了一种基于机器学习系统的数据驱动方法，该方法使用的数据集是从参考书目中选取的实验结果。使用库克距离法检测出数据集的离群点，并将其从原始数据集中删除，原始数据集由 113 个实例和 11 个输入变量组成。在处理后的数据集中，对 17 种机器学习方法进行了训练，通过超参数调整进行了优化，并在测试集上进行了比较。最有效的模型是 XGBoost 和 CatBoost 方法的优化实例，这两种方法结合成一个投票模型，充分利用了多个回归器的预测能力。最终的混合模型显示出卓越的预测能力，其判定系数（R2）为 0.95，平均绝对百分比误差为 8.03%。此外，还将该模型的预测结果与现有的分析关系进行了比较，发现该模型在所有模型中表现最佳。随后，应用机器学习解释方法，找出预测因子对目标输出的影响。Am、ft 和 n⋅tf 被确定为最重要的预测因子，主要对剪切能力有积极影响。最后，所构建的机器学习系统被用于一个用户友好型网络应用程序中，以方便专业人员和研究人员访问和使用。

Construction activities significantly impact natural resources and the environment, accounting for 40 % of global energy consumption and 36 % of carbon emissions. This study evaluates the environmental impacts of various primary construction materials by leveraging more original and comprehensive Environmental Product Declarations (EPDs) and incorporates insights from prevvious research to summarize effective mitigation strategies. Analyzing the environmental impact per unit mass is a critical step toward building-level assessments, enabling the strategic replacement of high-pollution materials with lower-impact alternatives to optimize environmental outcomes. The quantitative analysis of data from 180 EPDs indicates that aluminum and steel have the highest median total environmental impacts per unit mass, followed by plastics, while wood, cement, and concrete have relatively lower impacts. Overall, Abiotic Depletion Potential (ADP) and Global Warming Potential (GWP) are identified as the primary environmental impacts of construction materials. At the building level, the environmental footprint varies based on the quantity of each material used, leading to substantial overall impacts. Furthermore, this study explores the relationships between different environmental impacts, finding positive correlations between GWP and Primary Energy Non-Renewable Energy (PENRE), Acidification Potential (AP), and Photochemical Ozone Creation Potential (POCP). A comprehensive literature review identifies the key environmental hotspots and mitigation strategies for high-impact materials such as aluminum, steel, cement, and concrete. Common strategies include innovative production methods, waste recycling, carbon capture and storage (CCS), and the development of low-carbon materials. By integrating quantitative EPDs analysis with a qualitative literature review, this research provides a holistic understanding of the environmental burdens of construction materials, offering a valuable framework for developing sustainable policies and practices within the construction industry.

建筑活动对自然资源和环境有重大影响，占全球能源消耗的 40% 和碳排放的 36%。本研究通过利用更原始、更全面的环境产品声明（EPD），评估了各种初级建筑材料对环境的影响，并结合先前研究的见解，总结了有效的缓解策略。分析单位质量对环境的影响是进行建筑级评估的关键一步，可以战略性地用影响较小的替代品取代高污染材料，从而优化环境成果。对 180 份 EPD 数据的定量分析表明，铝和钢的单位质量总环境影响中值最高，其次是塑料，而木材、水泥和混凝土的影响相对较低。总体而言，非生物损耗潜能值（ADP）和全球变暖潜能值（GWP）被认为是建筑材料对环境的主要影响。在建筑层面，环境足迹因每种材料的使用量而异，从而产生巨大的总体影响。此外，本研究还探讨了不同环境影响之间的关系，发现全球升温潜能值与不可再生能源一次能源（PENRE）、酸化潜能值（AP）和光化学臭氧生成潜能值（POCP）之间存在正相关关系。综合文献综述确定了铝、钢、水泥和混凝土等高影响材料的主要环境热点和减缓战略。常见的策略包括创新生产方法、废物回收利用、碳捕获与封存（CCS）以及开发低碳材料。通过将定量环境影响指标分析与定性文献综述相结合，本研究提供了对建筑材料环境负担的整体理解，为建筑行业制定可持续政策和实践提供了宝贵的框架。

This study analyzes the CO2 equivalent emissions of a LEED-certified nearly Zero Energy Building (nZEB) using a simplified Life Cycle Assessment (LCA) methodology, aligned with EN 15978. Focusing on the building's energy performance across its life cycle, the study demonstrates that in 2022, 95 % of the energy used for heating came from renewable sources, which decreases to 86 % by 2050 due to milder winters. However, the need for cooling increases by 9 % over the same period due to hotter summers. By 2050 and 2080, if the EU transitions to renewable electricity, the operational Global Warming Potential (GWP) could approach zero. The study highlights that embodied emissions (69 %) outweigh operational emissions (31 %) in 2022, emphasizing the need to reduce embodied GWP through material reuse and recycling. Notably, concrete and aluminum were found to contribute the most to embodied emissions. The research also shows that nZEBs can exceed the EU's 2030 energy targets, with renewable energy contributing 67 % of the building's total consumption. As climate change favors nZEB performance, the operational emissions will trend towards zero, but embodied emissions will become increasingly significant. To achieve the EU's zero-emission goals, it is crucial to prioritize reducing embodied GWP in future nZEBs. This study underscores the importance of nZEBs in mitigating climate change impacts, offering a pathway toward sustainable construction and energy efficiency.

本研究采用符合 EN 15978 标准的简化生命周期评估 (LCA) 方法，分析了一栋经 LEED 认证的近零能耗建筑 (nZEB) 的二氧化碳当量排放量。研究重点关注建筑在整个生命周期内的能源表现，结果表明，在 2022 年，95% 的供暖能源来自可再生能源，到 2050 年，由于冬季气候更加温和，这一比例将降至 86%。然而，由于夏季更加炎热，同期制冷需求增加了 9%。到 2050 年和 2080 年，如果欧盟过渡到使用可再生电力，运行时的全球变暖潜能值（GWP）将趋近于零。该研究强调，2022 年的内含排放量（69%）超过了运行排放量（31%），强调了通过材料再利用和回收来降低内含全球升温潜能值的必要性。值得注意的是，混凝土和铝被认为是造成内含排放最多的材料。研究还表明，nZEB 可以超过欧盟 2030 年的能源目标，可再生能源占建筑总消耗量的 67%。由于气候变化有利于 nZEB 的性能，运行排放将趋向于零，但内含排放将变得越来越重要。为了实现欧盟的零排放目标，在未来的 nZEB 中优先减少内含 GWP 至关重要。这项研究强调了 nZEB 在减缓气候变化影响方面的重要性，为实现可持续建筑和能源效率提供了一条途径。

Most of the Greenlandic building stock comprises residential houses and apartments. Consequently, the indoor environment in Greenlandic office buildings has not been subject to wide-ranging investigations. The purpose of this study was to investigate the indoor environment in office buildings in Greenland and to characterise the buildings, their indoor environment, and occupant well-being, health and self-assessed performance. This was done through a post occupancy evaluation (POE), where 22 office buildings, including 70 offices in Nuuk and Sisimiut, were evaluated based on indoor environment measurements and questionnaires of occupants' perceived indoor environment. This was compared with data and results from a related study in office buildings in Denmark (26 office buildings, including 83 offices) collected in the same period. The Danish office buildings performed slightly better than the Greenlandic office buildings regarding the perceived indoor environment. The measured indoor environment differed in performance between the countries when benchmarking towards the requirements and guidelines of the Danish Working Environment Authority (DWEA). It was concluded that the office buildings in Greenland did not differ much from the office buildings in Denmark regarding the measured and perceived indoor environment.

格陵兰的大部分建筑都是住宅和公寓。因此，格陵兰办公楼的室内环境尚未得到广泛调查。本研究的目的是调查格陵兰办公楼的室内环境，并描述这些建筑、其室内环境、居住者的幸福感、健康状况和自我评估的表现。这项工作是通过入住后评估（POE）完成的，根据室内环境测量结果和居住者对室内环境感知的调查问卷，对 22 座办公楼（包括努克和西西米乌特的 70 座办公楼）进行了评估。评估结果与同期收集的丹麦办公楼（26 座办公楼，包括 83 间办公室）的相关研究数据和结果进行了比较。在感知室内环境方面，丹麦办公楼的表现略好于格陵兰办公楼。如果以丹麦工作环境管理局（DWEA）的要求和指导方针为基准，各国测量的室内环境表现有所不同。结论是，格陵兰的办公楼与丹麦的办公楼在测量和感知的室内环境方面差别不大。
