Abstract: An inorganic mortar system for chemical fastening of an anchor in mineral substrates can contain at least one hard aggregate having a Mohs-hardness of greater than or equal to 8. The inorganic mortar system contains a curable aluminous cement component A and an initiator component B for initiating the curing process. Component A contains at least one blocking agent selected from boric acid, phosphoric acid, metaphosphoric acid, phosphorous acid, phosphoric acid, and salts and mixtures thereof. Component B contains an initiator, at least one retarder, at least one mineral filler, and water. The use of at least one hard aggregate having a Mohs-hardness of greater than or equal to 8 in an inorganic mortar increases load values and reduces shrinkage. A method can be used for chemical fastening of an anchor, preferably of metal elements, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete, or natural stone.

Abstract: A non-polar reaction resin mixture can be used to improve the adhesion of a mortar composition based on radically polymerizable compounds, in particular based on urethane (meth)acrylates, on the surface of semi-cleaned and/or damp boreholes in mineral substrates. The use of a non-polar reaction resin mixture in the corresponding mortar composition reduced the sensitivity thereof to dampness and inadequate cleaning conditions, so that mortar compositions are obtained overall which are characterized by improved robustness against external influences.
