C³ - V2.5A


            Carbon Concrete Composite C³ – Load adapted carbon rebars
            for an economical use in the construction industry



            The aim of the project C³ - V2.5A was the further geometric development and   Period

            of adapted economic manufacturing technologies for a large-scale use in the
            construction industry. The focus was on the targeted exploitation of the high   Project management
