Abstract:
After a brief reminder of the main characteristics of UHPFRC and of the history of their development, this paper presents the 2013 AFGC recommendations on UHPFRC, with emphasis on developments based on practical experience and on research carried out during the last decade. The paper then presents the progress of French standardization on UHPFRC and a summary of the similarities and main differences between normal fibre-reinforced concrete and UHPFRC. It presents specific topics which have to be examined in order to formulate intermediate fibre-resistant concrete (between HPFRC and UHPFRC) and/or to formulate UHPFRC with a lower fibre content combined with traditional reinforcement. The paper ends with a summary of the technological breakthroughs brought about by UHPFRC with respect to both design methods and implementation processes.
