Abstract: A multi-component kit for a curable composition for fixing purposes, comprising an epoxy component (a), which comprises curable epoxides, and a hardener component (b), which comprises a Mannich base formulation, and the use of Mannich base formulations and, especially, further additives in hardener components for epoxy resins, the Mannich base formulation having specific properties (viscosity, H equivalents, content of free phenol derivatives). The multi-component kits according to the invention can be used within a broad temperature range and enable mortar compositions to be produced which, after curing, exhibit a particularly large tolerance range for temperatures and exhibit particularly high bond stress values at low temperatures and, especially, also at high temperatures.

Abstract: The invention relates to an anchoring arrangement (1) having an anchor rod (2) which is anchored with mortar (3) in a bore (4) in an anchoring substrate (5) (concrete). The anchoring arrangement (1) is crack-resistant when the following conditions are fulfilled: bore ? ? diameter diameter ? ? of ? ? anchor ? ? rod * bond ? ? stress ? 14 ? N mm 2 ? ? and ( I ) 0.4 ? diameter ? ? of ? ? anchor ? ? rod bore ? ? diameter ? 0.85 .

Abstract: The invention relates to multi-component kits, comprising at least two components, which include mutually complementary precursors of curable reactive resins; to the use of appropriate combinations of complementary precursors at the desired site of use, especially in the form of those kits, for producing synthetic mortars; to obtainable synthetic mortars; and to methods comprising the use of those kits in fastening technology.

Abstract: The invention relates to new resins characterised by a content of curable urea derivatives; to new synthetic mortars obtainable using them; to kits for producing the synthetic mortars; to the use of the resins or synthetic mortars in fastening technology; and also to new methods of fastening which comprise the use of those resins or synthetic mortars.

Abstract: The two-component composition for chemical fastenings consists of a first component and a second component separate from the first component. The first component contains a free-radical-curable synthetic resin, which is a mono-acrylate or monomethacrylate of an alkoxylated bisphenol having a viscosity of 100 to 5000 mPa·s at 23° C. The second component is a curing agent for the synthetic resin, such as dibenzoyl peroxide or methyl ethyl ketone peroxide. The first component may also include an accelerator. Good adhesion characteristics in wet concrete are provided by the adhesive composition because a monoacrylate and/or monomethacrylate of an alkoxylated, especially an ethoxylated or propyloxylated, bisphenol is used as the curable synthetic resin.

Abstract: A fixing element providing a reinforcement connection with a secondary action and settable in a drill hole by a hardenable composition the fixing element has a reinforcement rod, and at least one conical sleeve provided on the reinforcement rod, the at least one conical sleeve having a segment-shaped construction.
