This seminar covers the framework and recent updates within CEN/TC 154 regarding aggregates and their standards. Key highlights include the organization led by Colin Loveday, the active participation of multiple CEN countries, and a detailed overview of product and test method standards such as EN 13139, EN 12620, and EN 13383. Current efforts include amendments for incorporating recycled aggregates, revisions of existing standards, and the development of new test methods. The seminar aims to ensure comprehensive understanding and compliance with regulations governing aggregates.
