Special Issue Information

Dear Colleagues,

The convergence of advanced intelligent technologies with sustainable engineering principles is considered by engineers, scholars and governors to be a transformative pathway for the traditional architecture, engineering, and construction (AEC) industries. Many new ideas, concepts and technologies, such as generative design, low-carbon construction, sustainable urban construction, 3D print construction, digital twin of engineering, building robotics, industrialized building, etc., have been created and developed in the civil engineering field, including architectures, structures and constructions. This Special Issue aims to promote the high-quality works in developing and studying intelligent and sustainable technology or methods related to architectures, structures and constructions, with a focus on state-of-the-art progress, development, and new trends.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • AI and machine learning method in AEC
  • Low-carbon assessment and management of buildings
  • Sustainable strategies for AEC
  • 3D print construction
  • Intelligentization of construction machine
  • Building robotics
  • Engineering digital twin
  • Resilience and sustainability of buildings and infrastructures
  • Industrialized buildings

We look forward to receiving your contributions.

The construction industry contributes significantly to global CO2 emissions, primarily due to the production of ordinary Portland cement (OPC). As a sustainable alternative, geopolymer concrete, utilizing industrial by-products, such as ground granulated blast furnace slag (GGBFS) and fly ash (FA), has attracted increasing attention. However, studies on the post-fire behavior of high-strength slag–fly ash-based geopolymer concrete (HSSFGC) remain limited. In this study, two HSSFGC mixtures with FA contents of 10% and 30% were prepared and exposed to elevated temperatures of 100 °C, 300 °C, 450 °C, and 600 °C. After natural cooling, mass loss, ultrasonic pulse velocity (UPV), residual compressive strength, and microstructural evolution were investigated using XRD, FTIR, TGA, SEM, and EDS techniques. The results show that as temperature increases, mass loss and internal defects also increase, accompanied by deterioration of the interfacial transition zone (ITZ). At 100–300 °C, specimens with higher FA content exhibited improved residual compressive strength due to secondary geopolymerization of unreacted FA. However, above 300 °C, all specimens experienced significant strength degradation, with residual compressive strength at 600 °C reduced to 57% for FA-10 and 49% for FA-30 of their respective room-temperature values. This mix-specific difference, attributed to higher pore connectivity and more severe dehydroxylation in FA-30. These findings reveal the temperature-dependent degradation mechanisms of HSSFGC and provide a theoretical basis for post-fire assessment and sustainable engineering applications. Full article
