Abstract
A foamable, 2-component mortar composition is used to fix tie bars and similar anchoring means in boreholes, especially in hollow checker firebrick. The mortar composition is composed of a reactive resin, a curing agent component, as well as a foaming agent. The volume of the mortar composition required for the anchoring can be reduced significantly with the inventive composition. This is particularly important for anchorings which cross hollow checker firebrick.
