Abstract: A nozzle, including a support member and a nozzle boot surrounding at least a portion of the support member, the nozzle boot having a nozzle boot inlet and a nozzle boot outlet spaced from the nozzle boot inlet and a volume between the nozzle boot inlet and the nozzle boot outlet, the nozzle boot being expandable upon the introduction of fluid into the volume, and collapsible upon withdrawal of fluid from the volume. Also disclosed is a method of removing unwanted concrete from a surface by creating tensile stress to concrete adhered to that surface by causing the surface to expand, and a system for injecting fluid (s) into a rotating drum.
