| Zusammenfassung: | The element (11) i.e. roof bolt, has a hollow cylindrical receiving body (12), which includes a drilling head (16) at an end (13). The receiving body includes a hardener (27) and a reactive resin (28), which is supported from each other separately. The reactive resin includes two different formulations (29, 30) that are arranged in the receiving body. One of the formulations hardens rapidly in a mixed condition with the hardener located in a setting direction (S) of a fastening element, and other formulation hardens slower in the mixed condition with the hardener. |
