The present invention describes a multi-component inorganic anchoring system for a chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, comprising a curable powdery aluminous cement component A and an initiator component B in aqueous-phase for initiating the curing process, component A further comprising calcium carbonate, and component B comprising an accelerator constituent and water, characterized in that the calcium carbonate comprised in component A has an average particle size in the range of from 0.5 to 150 µm. Moreover, the present invention pertains to a use of calcium carbonate having an average particle size in the range of from 0.5 to 150 µm in an multi-component inorganic anchoring system to increase load values as well as to a method for a chemical fastening of anchoring means, preferably of metal anchors and post-installed reinforcing bars, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone.
