Abstract

A two-component system for forming adhesive bonds or for chemical anchoring comprises a curable binder component A and an activator component B. The component A comprises: A-1) an inhibited hydraulic binder selected from among calcium aluminate cement, calcium sulfoaluminate cement and mixtures thereof; the component B comprises: B-1) a curing activator. At least one of the components A and/or B comprises: V-1) an organic binder; and V-2) a filler having a Mohs hardness of at least 5. The system is an aqueous system which is unproblematical from a health point of view. It is easy to process and quickly attains high strengths.
