Summary
The construction industry generates a large amount of construction and demolition waste, while also consuming enormous quantities of natural aggregates and cement-based materials. Promoting the sustainable use of recycled aggregates in concrete is therefore an important pathway to reduce natural resource consumption, lower environmental impacts, and support circular construction. However, the wider engineering application of recycled aggregate concrete still faces challenges related to mechanical performance, durability, long-term service behavior, and standardization.
This Special Issue, "Sustainable Recycled Aggregate Concrete: Performance and Durability", aims to collect high-quality research on the design, preparation, characterization, performance evaluation, durability enhancement, and engineering application of recycled aggregate concrete. The focus is placed on innovative materials, mix design methods, modification technologies, and performance improvement strategies that can enhance the mechanical properties, durability, sustainability, and practical applicability of recycled aggregate concrete.
We welcome interdisciplinary contributions related to recycled coarse aggregates, recycled fine aggregates, recycled concrete powder, construction and demolition waste, supplementary cementitious materials, industrial by-products, fiber-reinforced recycled aggregate concrete, geopolymer recycled aggregate concrete, low-carbon binders, carbonation treatment, surface modification, and advanced characterization methods. Particular attention will be given to studies that combine experimental investigation, microstructural analysis, mechanical testing, durability assessment, life-cycle assessment, numerical modeling, and engineering demonstration.
This Special Issue also strongly encourages studies that connect recycled aggregate concrete with structural performance, long-term durability, repair and rehabilitation, intelligent construction, digital design, sustainability assessment, and practical infrastructure applications.
We invite original research articles, review papers, short communications, but not limited to, the following topics:
· Mechanical properties of recycled aggregate concrete;
· Durability and long-term performance of recycled aggregate concrete;
· Mix design optimization for recycled aggregate concrete;
· Surface treatment and modification of recycled aggregates;
· Carbonation treatment and CO₂ curing of recycled aggregates or recycled aggregate concrete;
· Recycled fine aggregates, recycled coarse aggregates, and recycled concrete powder;
· Fiber-reinforced recycled aggregate concrete;
· Geopolymer and alkali-activated recycled aggregate concrete;
· Supplementary cementitious materials and industrial by-products in recycled aggregate concrete;
· Shrinkage, creep, cracking behavior, and fracture properties;
· Bond behavior between recycled aggregate concrete and reinforcement;
· Structural performance of recycled aggregate concrete members;
· Chloride penetration, freeze-thaw resistance, sulfate attack, and carbonation resistance;
· Life-cycle assessment, carbon footprint evaluation, and environmental impact analysis;
· Numerical modeling, machine learning, and AI-assisted prediction of recycled aggregate concrete performance.
We look forward to receiving your valuable contributions to this Special Issue and to advancing the sustainable development and engineering application of recycled aggregate concrete for durable and low-carbon infrastructure.
