Multi-component inorganic anchoring system based on aluminous cement

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. Component A further includes calcium carbonate and component B includes an accelerator constituent and water. The calcium carbonate in component A has an average particle size in the range of from 0.5 to 150 μm. Methods can be utilized for using calcium carbonate having an average particle size in the range of from 0.5 to 150 μm in a multi-component inorganic anchoring system to increase load values. Methods can also be utilized for chemical fastening of anchors, such as metal anchors and post-installed reinforcing bars, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete, or natural stone.
