Summary
The path towards net-zero construction necessitates the development of sustainable cementitious materials that reduce carbon emissions and optimize resource efficiency and circular economy practices. Among industrial byproducts, steel slag has emerged as a highly promising precursor due to its abundance, mineral composition, and ability to replace traditional cement-based products. Recent advancements in geopolymerization and alkali activation technologies enable efficient use of steel slag to produce sustainable, low-carbon construction materials with enhanced mechanical properties and durability. Beyond waste management, geopolymerization and alkali activation technologies help mitigate greenhouse gas emissions, preserve natural resources, and implement circular economy practices in construction.
This Special Issue aims to highlight recent scientific and technological advances in steel slag-based geopolymers and alkali-activated materials for sustainable construction. Particular emphasis will be placed on industrial waste valorization, carbon footprint reduction, and life cycle assessment (LCA) as key approaches for developing sustainable construction materials.
Topics of interest include, but are not limited to:
· Steel slag-based geopolymerization and alkali-activation technologies
· Net-zero and low-carbon construction materials
· Circular economy and industrial waste valorization
· Life cycle assessment (LCA) and environmental sustainability
Original research articles, comprehensive reviews, and engineering case studies addressing these themes are warmly welcomed.
