Proceedings of the 79th RILEM Annual Week & ICONS 2025

This volume gathers the latest advances, innovations and applications in the field of sustainable construction materials and structures, as presented by leading international researchers and engineers at the 79th RILEM Annual Week, held in Hanoi, Vietnam on August 24-28, 2025. The International Conference on Advances in Engineering and Technology for Sustainable Development (ICONS 2025) was held along with the RILEM Annual Week. It covers topics such as supplementary cementitious materials, durability and Life Cycle assessment in urban and marine conditions, additive manufacturing of concrete in construction, structural performance and design, non-Portland cements and Alkali activated cementitious materials and eco-concrete, cultural heritage, non-destructive testing techniques, bituminous materials, and construction materials (polymers, timber, bamboo, recycling and masonry). The contributions, which were selected through a rigorous international peer-review process, share exciting ideas that will spur novel research directions and foster new multidisciplinary collaborations.
