Abstract: A multi-component inorganic capsule anchoring system can be used for chemical fastening of anchors, bolts, screw anchors, screw bolts, and post-installed reinforcing bars in mineral substrates. The multi-component inorganic capsule anchoring system contains a curable powdery Portland cement clinker-based component A and an initiator component B in aqueous-phase for initiating the curing process. The powdery Portland cement clinker-based component A further contains a sulfate agent. The initiator component B contains water and optionally, a plasticizer.

Abstract: A two-component inorganic injection mortar system includes a curable aqueous-phase aluminous cement component A and an initiator component B in aqueous-phase for initiating the curing process. Component A includes at least one blocking agent which is phosphoric acid, metaphosphoric acid, phosphorous acid or phosphonic acid, at least one plasticizer and water. Component B includes an initiator, at least one retarder, at least one mineral filler and water. The curable aqueous-phase aluminous cement component A includes calcium aluminate cement having an average particle size in the range of from 0.5 to 15 ?m. A two-component system, which is ready-for-use, can be used for chemical fastening of anchors, such as metal elements, or in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone.

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.
