Zusammenfassung:A cartridge (18) for containing a multi-component adhesive system for use in a rock anchor (10) includes a rigid tubular housing (19) which has an input end and an opposed output end within which at least one compartment (26A, 26B) is defined. The compartment contains an adhesive component of the system. The at least one compartment yields to volumetrically reduce, under fluid pressure created by a fluid input (47) into the housing, thereby to extrude the adhesive components.
