Abstract:
Steel-fibre-reinforced concrete (SFRC) has been known since the sixties and has been used for structures for the past 30 years; SFRC has therefore become a subject of intensive research and development. A Danish consortium on sustainable concrete structures was involved in several demonstration projects using steel-fibre-reinforced self-compacting concrete (SFRSCC) to prepare guidelines on design and execution of SFRC and SFRSCC structures. This paper summarizes and presents selected projects with the application of steel-fibrereinforced concrete and self-compacting concrete. The paper describes and discusses the design methodology, relevant aspects and practical experiences from the construction of bridge, tunnel and foundation projects. Special attention is paid to the cost savings, corrosion resistance and durability aspects of the SFRC application, as the demand for efficient and long-term sustainable concrete structures is rapidly growing, with the common expectation of a service life on the order of minimum 100-120 years.
