Abstract:
A method for reinforcing a structure comprising the following steps:
preparation of UHPFRC comprising a cement precursor mix, of water, a fluidizing agent and metal fibers,
transporting the UHPFRC by pumping to a suitable spray nozzle,
spraying the mix onto a surface of the structure by the addition of a compressed air stream in the spray nozzle.
