Abstract:
A major step forward has been made by successfully spraying ultra-high-performance concrete in every orientation. Over the past four years, the innovative technique of sprayed UHPC has been developed and improved as a result of several recent projects. The characteristics typically obtained will be presented, as well as the methods used to justify the structures and the lessons learnt from 6 repair sites of corrugated steel culvert, which have suffered from corrosion without being excessively deformed. Broader fields of application will be discussed and prospects for development will be opened up. Aspects related to innovations, material and structural design; application potentials will thus be covered.
