Abstract
A method involves using at least one salt (S) selected from the salts of nitric acid, salts of nitrous acid, salts of halogens, or salts of trifluoromethanesulfonic acid, as an accelerator in a multi-component epoxy resin compound for the chemical fastening of construction elements and/or anchoring elements. Another method involves the chemical fastening of construction elements and anchoring elements, such as anchor rods, anchor bolts, rods, sleeves, reinforcing bars, screws, and the like in boreholes in various substrates.

1-15. (canceled)
A method, comprising:
- accelerating an epoxy resin compound by combining the epoxy resin compound with at least one salt (S) comprising at least one salt of trifluoromethanesulfonic acid.
A method for the chemical fastening of a construction means and/or an anchoring material, the method comprising:
- chemical fastening of the construction means and/or anchoring material with a multi-component epoxy resin compound which comprises an epoxy resin component (A) which contains at least one curable epoxy resin, and a curing agent component (B) which contains at least one amine which is reactive to epoxy groups,
- wherein the epoxy resin component (A) and the curing agent component (B) are separate from one another so as to prevent a reaction, and then combined to cure, and
- wherein the epoxy resin component (A) and/or the curing agent component (B) comprises at least one salt (S) as an accelerator, and
- wherein the at least one salt (S) comprises at least one salt of trifluoromethanesulfonic acid.
A composition, comprising:
- an epoxy resin compound and at least one salt (S) comprising at least one salt of trifluoromethanesulfonic acid.
