Provided is a composition for a rapid setting sprayable cement material as well as the process and system for mixing and placing said cement material. The composition comprises a sprayable mixture of cement forming ingredients such as silicon dioxide, magnesium oxide, and an aqueous metal phosphate solution. The process for mixing and placing said cement material uses serially connected dry material feed receptacles (R1) and (R2) which are independently pressurizable and are isolatable from ambient conditions after loading to provide substantially increased throughput volume. The receptacles communicate the composition to a fluidizing element (C1) in which the material is fluidized before being formed into a slurry and atomized via spray nozzle (45).
L'invention concerne une composition de matériau à durcissement rapide et pulvérisable, à base de ciment, ainsi que le procédé et le dispositif servant à mélanger et à mettre en place ledit matériau. Cette composition comprend un mélange pulvérisable d'ingrédients de constitution de ciment, tels que du dioxyde de silicium, de l'oxyde de magnésium et une solution aqueuse de phosphate de métal. Le procédé de mélange et de mise en place dudit matériau fait appel à des réceptacles de charge de matériau sec reliés en série (R1) et (R2), qu'on peut mettre sous pression individuellement et isoler du milieu ambiant après leur chargement, de façon à augmenter sensiblement le volume de production. Les réceptacles transfèrent la composition à un élément de fluidification (C1) dans lequel le matériau est fluidifié avant d'être préparé en boue liquide et pulvérisé au moyen d'un pulvérisateur (45).
