MIMC achieves superior carbonation efficiency (up to 90–95%) under mild conditions, ensuring environmental sustainability, safety, and cost-effectiveness. Key factors include microbial characteristics, steel slag properties, and process conditions. The review discussed how MIMC can enhance the properties of carbonated steel slag by modifying mineralogy and microstructure, improving physical and mechanical attributes, and optimizing environmental performance. Moreover, the application of MIMC-treated steel slag in engineering construction was examined.

To address the common detection challenges like fuzzy boundaries and partial occlusion, an improved semantic segmentation-based framework was proposed for real-time progress tracking.

A collaborative end-cloud device captures real-time images of the mixer tail, formalizing homogeneity evaluation as a semantic image segmentation task. Our method detects non-paste and non-homogeneous areas, defining a non-homogeneity factor as their proportion to the paste area. Using Gaussian process regression, the system predicts the factor’s probability and defines a homogeneity metric.

To evaluate the potential of such technologies, one major input data for models and calculations is the available roof area, yet the literature shows a huge knowledge gap in this regard. Therefore, this paper contributes to filling this gap by estimating the roof availability over the period 2022–2060, using the detailed regional projections of the BISE (Building Integrated Solar Energy) model. Our results show that the roof area is likely to increase globally and in most of the analysed regions over the forthcoming decades, driven primarily by newly built tertiary buildings. In European context, the future increase of commercial/public rooftops is projected to be more pronounced for the western countries, although the overall growth is predicted to be slightly offset by shrinking residential rooftops both in the western and eastern regions. This study also demonstrates that despite the shading-related uncertainties of the estimation, the dimension of the available rooftop area could ensure significant potential for energy production and thermal regulation.</div></div>","PeriodicalId":34137,"journal":{"name":"Developments in the Built Environment","volume":"21 ","pages":"Article 100607"},"PeriodicalIF":6.2,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
