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 ?m. Methods can be utilized for using calcium carbonate having an average particle size in the range of from 0.5 to 150 ?m 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.

Abstract: A multi-component inorganic capsule 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 aqueous phase for initiating a curing process. The powdery aluminous cement component A is an aluminous cement component based on powdery calcium aluminate cement, and component B includes an accelerator constituent and water. A method can be utilized for chemical fastening of an anchor, such as metal anchors and post-installed reinforcing bars, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete, or natural stone.

Abstract: A hardener composition can be used for a reactive resin system containing a reactive resin based on radically curable, ethylenically unsaturated compounds. The hardener composition contains a hardener for the reactive resin and a filler mixture. The filler mixture is composed of a first filler having a first average particle size d50,1 and a second filler having a second average particle size d50,2. The first average particle size d50,1 of the first filler is greater than the second average particle size d50,2 of the second filler (d50,1>d50,2). The ratio d50,1 to d50,2 (d50,1:d50,2) is in the range of 8:1 to 100:1. The filler mixture is useful, and a reaction resin system can contain the hardener composition.
