Claim 10:
11. A method of chemical fastening to increase load values, the method comprising:
chemical fastening of an anchor or post-installed reinforcing bar in a mineral substrate with calcium carbonate having an average particle size in a range of from 0.5 to 150 μm in a multi-component inorganic anchoring system,
wherein the multi-component inorganic anchoring system comprises a curable powdery aluminous cement component A and an initiator component B for initiating a curing process, wherein the multi-component inorganic anchoring system provides increased load values compared to a multi-component anchoring system not having said calcium carbonate having said average particle size, 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.
