Abstract (en)

[origin: EP1000719A2] The spray concrete producing process involves producing a premix of binder and fine-grain additive, transporting it to the site and mixing a coarse-grain additive, brought in from the vicinity of the site, with it. The device used to implement the process has two pressure silos (3, 4), each with an issuing unit, a mixing device (8) and a transporting line (23) taking the mixture to a spray jet (24).
