Abstract: A setting method of anchoring a fastening element (11; 41) in a constructional component (21) with a hardenable multi-component mass (31) includes drilling a borehole (22) in the constructional component (21) with a drill (36) until a borehole depth (T), which is at least by 5% greater than a necessary anchoring length (L) of the fastening element (21; 41), is reached; introducing the hardenable multicomponent mass (31) in the uncleaned borehole (22), inserting, in the borehole (22) the fastening element (11; 41) with its mixing section (13; 43) first, and power-driving the fastening element (11; 41) into the filled borehole (22) with a rotary driving tool, with intermixing of the hardenable multi-component mass (31) with drillings (23) remaining in the borehole (22), until the necessary anchoring length (L) of the fastening element (11; 41) is reached.

Abstract: A mortar mixture unit (1) for chemical attachment of anchoring means or members in boreholes includes an essentially cylindrical external cartridge (2), which can be destroyed when inserting the anchoring member into a borehole containing a cartridge. The cartridge (7) contains individual ingredients of a multi-component mortar including a binder means system (6, 8) and filling agents (7). The cartridge (2) is formed of a flexible material having a volume share amounting to less than 15% of the total volume of the mortar mixture unit (1), the volume share of the binder means system (6, 8) amounts to approximately 50% to 60% of the total volume of the mortar mixture unit (1) and the volume share of the filling agents (7) amounts to approximately 35% to 70% of the total volume of the mortar mixture unit (1).
