19 Claims

1. A multi-component inorganic anchoring system, comprising:

a curable powdery aluminous cement component A and an initiator component B in an aqueous-phase for initiating a curing process,

wherein component A further comprises calcium carbonate, and

component B comprises an accelerator and water,

wherein the calcium carbonate in component A has an average particle size in a range of from 0.5 to 150 μm, and

wherein component A comprises 9.1 to 50% weight percent of the calcium carbonate and at least 60 weight percent of the aluminous cement.
