ABSTRACT:
An anchoring cartridge suitable for use in anchoring a reinforcing or fixing element such as an anchor bolt in a borehole in a substrate contains a particulate liquid-settable solid component, such as a hydraulic cement, within a frangible liquid-impermeable casing. Through the solid component passes a discontinuous tube at least one end of which is located at one end of the cartridge so as to be in communication with the exterior. To activate the cartridge, it is placed within an activating liquid, such as water, which flows into the cartridge via the discontinuous tube and thus into contact with the solid component from within the cartridge over substantially its whole length, so that after a relatively short time, i.e. a few minutes, the activated cartridge can be positioned for use in a borehole. This discontinuous tube regulates the flow of activating liquid into the solid component and serves to ensure the formation of a self-setting grouting composition of substantially uniform strength when the cartridge is used in anchor bolting.
