Two-component mortar mass and use thereof

A two-component mortar mass, comprising:

• a resin component (A), which contains at least one radically curable resin as a curable constituent;
• and
• a curing component (B), which contains a curing agent for the radically curable resin of the resin component (A);
• wherein the radically curable resin is obtained by reaction of
• an at least difunctional component, which has two or more reactive groups (RG-A),
• with a silane intermediate compound and
• an ethylenically unsaturated compound,
• wherein the silane intermediate compound and the ethylenically unsaturated compound each have active functional groups (AG) that react with the reactive groups (RG-A), causing the formation of a covalent bond,
• wherein the silane intermediate compound is the reaction product of a cyclic organic compound selected from the group consisting of a cyclic anhydride, a cyclic carbonate, a cyclic thiocarbonate, a cyclic carbamate, a cyclic thiocarbamate, a cyclic urea, a lactone, a lactam and combinations thereof with a functionalized silane compound, which has at least one reactive group (RG-B),
• wherein the cyclic organic compound reacts with the reactive group (RG-B) of the functionalized silane compound, causing the formation of the silane intermediate compound having at least one functional active group selected from the group consisting of a carboxyl group, a hydroxy group and an amino group, and
• wherein the silane intermediate compound is reacted in a proportion of at least about 2 wt. % of the resin component (A), with reference to organic constituents of the resin component (A).
