Abstract
A multi-component inorganic anchoring system, for chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, includes a curable powdery aluminous cement component A and an initiator component B in an aqueous phase for initiating a curing process. The powdery aluminous cement component A includes an aluminous cement component based on powdery calcium aluminate cement and component B includes an accelerator constituent and water. Furthermore, at least part of the calcium aluminate cement of component A has an average particle size in the range of from 0.5 to 15 μm. Methods of using the calcium aluminate cement in a multi-component inorganic anchoring system to increase load values and methods for chemical fastening of anchors in mineral substrates can be performed.
