    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: Calcium carbonate which has an average particle size in the range of from 0.5 to 3 μm is used in an inorganic mortar system for a chemical fastening of anchors and post-installed reinforcing bars in mineral substrates. The system includes a curable aluminous cement component A and an initiator component B for initiating the curing process. The component A includes at least one blocking agent selected from phosphoric acid, metaphosphoric acid, phosphorous acid and phosphonic acids, at least one plasticizer, and water. The component B includes an initiator, at least one retarder, at least one mineral filler, and water. Moreover, the calcium carbonate increases load values. Further, a method is used for a chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, such as structures made of brickwork, concrete, pervious concrete or natural stone.

    Abstract: A reactive resin composition is described, comprising a resin constituent (A) comprising a free-radically polymerizable compound (a-1), a compound (a-2) which can react with an amine, and a bridging compound (a-3) having at least two reactive functionalities, one of which can be free-radically (co)polymerize and one of which can be react with an amine, and a hardener constitute (H) comprising at least one dialkyl peroxide (h-1) and at least one amine (h-2) where the resin constituent (A) and the hardener (H) or the resin constituent (A) and at least one dialkyl peroxide (h-1) and at least one amine (h-2) of the hardener (H) are spatially separated from one another, in order to prevent reaction prior to mixing of these components, which is characterized in that the hardener constituent (H) further comprises an accelerator mixture (B) consisting of a copper compound (b-1) and a 1,3-dicarbonyl compound (b-2), with the proviso that the resin composition is suitable for use for construction purposes, preferably for securing anchor thread bars, iron reinforcements, bushing or screws in boreholes in all kinds of substrata.

    Abstract: A multi-component mortar system contains a curable aqueous-phase aluminous cement component A and an initiator component B in aqueous-phase for initiating the curing process. Component A further contains at least one plasticizer, water, and at least one blocking agent selected from phosphoric acid, metaphosphoric acid, phosphorous acid, and phosphonic acids. Component B contains an initiator, at least one retarder, at least one mineral filler, and water. A multi-component system is useful, which is ready-for-use, for chemical fastening of anchoring means, preferably of metal elements, in mineral surfaces, such as structures made of brickwork, concrete, pervious concrete or natural stone as well as its use for chemical fastening of anchoring means.
