“…Advanced wireless sensor systems can provide real-time data on concrete temperature [194], humidity [195], and strength development [196], helping to ensure that the concrete maintains the necessary conditions for optimal curing and performance. These systems can also help identify potential issues early, allowing for timely corrective action [197]. Digital image correlation (DIC) techniques involve the use of high-resolution cameras and advanced image processing algorithms to measure the deformation and strain of concrete structures during curing and service life [198].…”

Cold weather conditions pose significant challenges to the performance and durability of concrete materials, construction processes, and structures. This paper aims to provide a comprehensive overview of the material-related challenges in cold weather concrete construction, including slow setting, reduced curing rate, and slower strength development, as well as frost damage, early freezing, and freeze–thaw actions. Various innovative materials and technologies may be implemented to address these challenges, such as optimizing the concrete mix proportions, chemical admixtures, supplementary cementitious materials, and advanced construction techniques. The paper also examines the impact of weather-related challenges for personnel, equipment, and machinery in cold environments and highlights the importance of effective planning, communication, and management strategies. Results indicate that the successful implementation of appropriate strategies can mitigate the challenges, reduce construction time, and enhance the performance, durability, and sustainability of concrete structures in cold and freezing temperatures. The paper emphasizes the importance of staying updated about the latest advancements and best practices in the field. Future trends include the development of smart and functional concrete materials, advanced manufacturing and construction techniques, integrated design, and optimization of tools, all with a strong focus on sustainability and resilience.

“…The structural design of formwork is another critical aspect of concrete construction, requiring a balance between different considerations such as safety, cost, and performance. One of the central aspects of formwork design is managing the form pressure exerted by the fresh concrete [66][67][68][69][70]. Form pressure is the pressure generated by fresh concrete as it is poured inside the formwork system during construction, and it is the decisive factor in formwork design, as the formwork must have the capacity to withstand the concrete's pressure without deformation or failure.…”

This study provides a comprehensive review of the engineering challenges of formwork in concrete construction. The paper investigates different formwork systems, their design based on form pressure, and the difficulties of form stripping. Alternative binders are gaining more and more interest by opening new opportunities for sustainable concrete materials and their impact on form pressure and concrete setting is also investigated in this paper. The discussion involves several engineering challenges such as sustainability, safety, and economy, while it also explores previous case studies, and discusses future trends in formwork design. The findings pinpoint that choosing an appropriate formwork system depends significantly on project-specific constraints and that the development of innovative materials and technologies presents significant benefits but also new challenges, including the need for training and regulation. Current trends in formwork design and use show promising possibilities for the integration of digital technologies and the development of sustainable and ‘smart’ formwork systems. Continued research within the field has the possibility to explore new formwork materials and technologies, which will contribute to the implementation of more effective and sustainable practices in concrete construction.

“…In addition, the concrete must have the necessary workability for uniform distribution in the formwork with dense textile reinforcement, as well as high strength to ensure the effective function of textile strings in the concrete [41,42]. As is known from global building practices, self-compacting concrete is used for the concreting of densely reinforced structures [43][44][45][46][47]. Consequently, the development of self-compacting, high-strength concrete using sea water, sea sand and sulphate-resistant cement is an urgent task.…”

In this study, a self-compacting high-strength concrete based on ordinary and sulfate-resistant cements was developed for use in textile-reinforced structural elements. The control concrete was made from quartz sand and tap water, and the sea concrete was made from sea water and sea sand for the purpose of applying local building materials to construction sites in the coastal area. The properties of a self-compacting concrete mixture, as well as concrete and textile-reinforced concrete based on it, were determined. It was found that at the age of 28 days, the compressive strength of the sea concrete was 72 MPa, and the flexural strength was 9.2 MPa. The compressive strength of the control concrete was 69.4 MPa at the age of 28 days, and the flexural strength was 11.1 MPa. The drying shrinkage of the sea concrete at 28 days exceeded the drying shrinkage of the control concrete by 18%. The uniaxial tensile test showed the same behavior of the control and marine textile-reinforced concrete; after the formation of five cracks, only the carbon textile reinforcement came into operation. Accordingly, the use of sea water and sea sand in combination with a cement with reduced CO2 emissions and textile reinforcement for load-bearing concrete structures is a promising, sustainable approach.
