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 μm. 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: A long-term stabilized aqueous initiator composition, which includes components for curing of a two-component mortar system composition. The long-term stabilized aqueous initiator composition includes an activator component that has an alkali and/or alkaline earth metal salt, an accelerator component that has a water-soluble alkali and/or alkaline earth metal salt, a retarder selected from citric acid, tartaric acid, lactic acid, salicylic, gluconic acid, and a mixture of these components, a mineral filler selected from a limestone filler, corundum, dolomite, alkaline-resistant glass, crushed stone, gravel, pebble, and a mixture of these components, a thickening agent, and water.

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.
