This book gathers the latest advances, innovations, and applications in the field of waste valorization within concrete manufacturing, as presented at the 1st International Conference on Concrete and Circular Economy (CCE), held in Hammamet, Tunisia on 10-13 April 2025. Topics include Sustainability of materials and structural systems, incl. waste, Valorization of demolition waste, Design with natural fibre composites, Recycling of used materials, Decarbonation of concrete industry, Eco-design and eco-construction, Digitalization and 3D concrete printing, Life cycle assessment, Eco-friendly binders with low CO2-emission. The contributions were selected through a rigorous peer-review process and offer a comprehensive, multidisciplinary overview of research on the application of circular economy principles in the concrete sector for sustainable construction.

Examines the transition to the circular economy by reusing concrete waste Investigates the valorization of demolition waste, recycling of used materials, decarbonation of concrete industry Gathers the proceedings of the 1st Int'l Conf. on Concrete and Circular Economy, Hammamet, Tunisia, 10-13 April 2025
