Abstract

A long-term stabilized aqueous initiator composition, which includes components for curing of a two-component mortar system composition. The long-term stabilized aqueous initiator composition includes an activator component that has an alkali and/or alkaline earth metal salt, an accelerator component that has a water-soluble alkali and/or alkaline earth metal salt, a retarder selected from citric acid, tartaric acid, lactic acid, salicylic, gluconic acid, and a mixture of these components, a mineral filler selected from a limestone filler, corundum, dolomite, alkaline-resistant glass, crushed stone, gravel, pebble, and a mixture of these components, a thickening agent, and water.
