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 the curable powdery aluminous cement component A comprises an aluminous cement component comprising powdery calcium aluminate cement, and
wherein initiator component B comprises an accelerator and water,
wherein at least part of the powdery calcium aluminate cement in component A has an average particle size in a range of from 0.5 to 15 μm.
