ABSTRACT:
A two-component mortar composition is described with a curable resin component containing at least one free radical-polymerizable resin, fillers, reactive diluents, solvents, accelerators and/or further conventional mortar components and, separated therefrom to inhibit reaction, a curing agent component for chemically fastening anchoring means in boreholes, characterized in that the resin component, in order to improve the adhesion to different mineral substrates of the borehole, contains a reactive diluent mixture of at least one hydroxyalkyl (meth)acrylate and at least one acetoacetoxyalkyl (meth)acrylate. Furthermore, the use of the two-component mortar composition for chemically fastening anchoring means in boreholes of different mineral substrates is also described.
