Special Issue Information

Dear Colleagues,

The construction industry increasingly embraces sustainability as a core principle, addressing urgent challenges such as resource depletion, waste accumulation, and carbon emissions. This Special Issue, titled "Utilization of Recycled Aggregates and Waste in Sustainable Concrete Materials", highlights innovative applications of recycled aggregates and various waste materials to develop sustainable concrete for diverse purposes. By promoting these materials, the issue contributes to advancing the circular economy, reducing the ecological footprint of construction activities, and fostering environmentally conscious building practices.

We invite original research, reviews, and case studies exploring various aspects of sustainable concrete, including but not limited to its mechanical, durability, structural, and microstructural properties. This issue will also examine the application of these materials in civil engineering structures, architectural designs, pavement systems, and other infrastructural projects. Furthermore, it aims to cover advancements in material processing, waste management, environmental assessment techniques, and their economic implications.

This Special Issue welcomes innovative and interdisciplinary approaches, including artificial intelligence and computational methods, to push the boundaries of sustainable construction practices. The findings will provide a valuable resource for researchers, engineers, and architects working to advance green and resilient infrastructure.

The growing generation of solid waste, driven by urbanization and industrialization, represents one of today’s greatest environmental challenges. The construction industry can play a key role in this scenario by incorporating recycling and waste reuse practices. Glass, a fully recyclable material, is still largely disposed of in landfills. A promising alternative is the use of ground glass in cementitious materials, partially or completely replacing cement or aggregates. Thus, in this paper, the effect of partially replacing Portland cement with ground glass of different colors including green, blue, transparent, amber, and colorful (all colors used mixed) in proportions of 15 and 35% in mortars was evaluated. The ground glasses were characterized by laser granulometry and chemical analysis. The properties of the mortars were then evaluated in the fresh and hardened state (apparent specific gravity, mechanical strength, water absorption, and open porosity). Regarding workability, the highest improvement observed was 6.8% for the 35% colored glass series compared to the reference series. In terms of entrapped air, there was an increase of up to 18.8% in the 35% green glass series. At 28 days of hydration, the 15% colored glass series obtained a 33% increase in flexural strength compared to the REF series. In the microstructure, it was found that a 15% glass presence was sufficient to reduce the portlandite index from 16.04 to 13.53, while a 35% glass presence was sufficient to reduce it to 7.51% portlandite, equivalent to a 54% reduction, suggesting significant potential for the reaction of the finer glass fractions with portlandite. This study suggests that the use of glass waste in a cementitious matrix can provide an environmentally appropriate alternative for recycling this material, contributing to a sustainable application and increased recycling rates of glass waste.

To advance the application of sustainable recycled aggregate concrete (RAC) in bridge engineering, this study introduces a novel reinforced RAC-filled circular steel tubular (RRACFCST) column, leveraging the dual confinement of an external steel tube and an internal reinforcement cage. Its primary novelty is a comprehensive analytical framework integrating a new theoretical model by using limit analysis, ferrule theory, and the twin shear unified strength theory. Then, a rigorously validated nonlinear finite element model that incorporated material nonlinearity and interface effects was used to validate the proposed theoretical model. The results demonstrate the significant performance of the steel reinforcement cage, which enhanced the axial bearing capacity by 17.86%, and an optimal recycled aggregate replacement rate of 70% yielded the bearing capacity, with 100% replacement still achieving a 13.3% higher capacity than unconfined conventional concrete, demonstrating how effective confinement can compensate for and overcome the inherent deficiencies of RCA. Conversely, larger diameter–thickness ratios would reduce the strength by 33.7%. These quantifiable findings provide critical design insights and a validated predictive tool, establishing the RRACFCST column as a promising and high-performance sustainable solution for bridge structures.

The construction industry plays a crucial role in socioeconomic development, but is also one of the sectors with the highest environmental impact due to intensive resource extraction, high energy demand, and greenhouse gas emissions. Life Cycle Assessment (LCA) is a strategic tool for quantifying and comparing environmental impacts associated with products and processes across their stages. This study analyzes the application of Life Cycle Assessment (LCA) to paving blocks through a systematic literature review, focusing on environmental indicators and common block compositions. Following the PRISMA protocol, 45 articles were selected from the Scopus and Web of Science databases. The results show that using industrial waste as a substitute for conventional materials enhances the sustainability of paving block production. A growing trend of studies addressing partial replacement of cement and aggregates was observed, reflecting circular economy practices in construction. Global Warming Potential and Cumulative Energy Demand were the most frequently reported impact indicators. These findings highlight that incorporating recycled materials is an effective approach to mitigating environmental impacts in the construction sector. Full article
