Abstract

A method includes 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 means. Another method includes 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.
