Abstract
A composite anchor has an anchoring rod and a crushable cartridge filled with two components of a hardenable bonding agent which include a mineral mortar component and a water component separated from one another by crushable separating means. When the cartridge with the separating means is crushed by the anchoring rods the components are mixed by the anchoring rod in order to fix the anchoring rod in a drilled hole. The water component has a thixotropic agent which is paste-like unless it is subjected to shear forces.
