Epoxy resin mixtures include at least one curable epoxy resin and at least one epoxide-acrylate hybrid molecule that bears at least one epoxy group and at least one acrylate group. A method is developed for chemical anchoring with the epoxy resin mixture in the resin component of a multi-component reactive resin composition. Furthermore, the multi-component reactive resin composition includes the epoxy resin mixture. A second method is developed for chemical anchoring with the multi-component reactive resin composition.
