“…These substitutes improve the longevity of concrete while simultaneously lowering CO 2 emissions. Diversifying alternatives such as fly ash and silica fume are investigated in studies conducted by [40]. Dixon et al [41] acknowledge the good benefits of the environment but also mention problems such as material unpredictability.…”

Manufacturing cement has a major impact on climate change, resource depletion, and pollution. Selecting sustainable cement alternatives is vital but entails difficult trade-offs between numerous variables. The objective of this study is to determine the most environmentally beneficial method of cement manufacturing by employing an integrated life cycle assessment multi-criteria decision-making technique. The LCA is employed to quantitatively evaluate the environmental effects of ten different methods of cement production across eighteen distinct categories. Meanwhile, the CRITIC weighted TOPSIS and EDAS MCDM approaches are utilized to rank the various alternatives by determining their proximity to the optimal solution. The LCA results showed that CEM III/A slag cement had lower environmental impacts than Portland cement. With a ranking score of 0.9094 and 1.7228 for EDAS and TOPSIS techniques, respectively, both MCDM identified CM10: ground granulated blast furnace slag (GGBFS) as the most recommended. In addition, midpoint characterization revealed that clinker production was responsible for 55% of the global warming impact. Based on these findings, slag cements are more environmentally friendly than Portland cement. Furthermore, an integrated LCA-MCDM approach offers a thorough sustainability evaluation that incorporates many aspects. Overall, this research shows that blast furnace slag cements, notably CM10, are ideal alternatives for reducing the environmental consequences of cement production in a variety of areas. This integrated methodology provides a systematic framework for making informed decisions in the production of sustainable cement.

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 presence of SiO 2 in microsilica, comprising more than 95% of its composition, facilitates the formation of a secondary gel of calcium silicate hydrates (CSH) during the hydration reaction. This process contributes to the enhancement of concrete’s physical and mechanical properties, as well as its durability [ 24 , 25 , 26 , 27 ].…”

The application of polymer materials in concrete structures is widespread and effectively used. However, there is a lack of a systematic knowledge base about the structure formation and properties of variatropic vibrocentrifuged modified fiber-reinforced concrete. The purpose of this work is the investigation of the influence of polypropylene (PF) and basalt fiber (BF) and modification with microsilica (MS) on the properties of variatropic concretes obtained using the synthesized vibration centrifugation technology. Test samples were made using vibration centrifugation technology, followed by sawing. Various types of fiber reinforcement were studied, both individually and in combination. To determine the degree of effectiveness of each recipe solution, the following main characteristics were monitored: the density and workability of concrete mixtures; the density of hardened composites; compressive strength (CS); bending strength (BS); water absorption (WA). In variatropic vibrocentrifuged concrete, the greatest efficiency is achieved with dispersed BF reinforcement in an amount of 1.5%. Compared to the control composition, the increase in CS was 8.50%, the increase in BS was 79.17%, and WA decreased by 27.54%. With PF reinforcement, the greatest effect was recorded at a dosage of 1.0%. The increase in CS was 3.16%, the increase in BS was 10.42%, and WA decreased by 17.39%. The MS modification showed the best effect with 8% replacement of part of the Portland cement. The increase in CS was 17.43%, the increase in BS was 14.58%, and WA decreased by 33.30%. The most effective and economically rational formulation solution for vibrocentrifuged concrete is combined fiber reinforcement in combination with the MS modification in the following quantities: BF—1.0%; PF—0.5%; MS—8%. The increase in CS was 22.82%, the increase in BS was 85.42%, and WA decreased by 37.68%.
