A method of anchoring a first object in a second object. The second object defines an opening. The first object has an insert portion that defines an insertion axis and has an outer shape that may form an undercut with respect to axial directions. The method includes inserting the insert portion in the opening, with a hardenable composition (prepolymer; mortar) between a wall of the opening and the insert portion, and causing mechanical vibration energy to impinge to cause the hardenable composition to undergo a chemical hardening process to yield a hardened composition, so that a first connection between the first object and the hardened composition and a second connection between the hardened composition and the second object results, whereby the first object is anchored in the second object. The first connection and/or the second connection may include an adhesive connection and/or a positive-fit connection.

A dry grout composition including a calcium aluminosulfate based hydraulic cement, a mineral filler, a thixotropic agent, and a superplasticizer agent. Also, an anchoring capsule, containing the dry grout composition, for use in anchoring reinforcing member dowel, or anchor elements in a hole of a substrate, and a method of use.

A fastening arrangement is made with a screw that has a shank, at least one thread helix being arranged on the shank, and a cured compound. The screw is arranged in a hole in a substrate, and a gap between the shank and the hole wall is filled with a cured aluminate-containing inorganic composition.

A fastening system for chemically fastening an anchor, the fastening system including a chemical anchor that is a ready-for-use two-component mortar system based on albuminous cement, and an anchor rod comprising an attachment region and an anchoring region. The anchor rod is insertable into a borehole and has a profiled section including a plurality of expansion sections disposed axially in a row which are conically shaped.

A new adhesive composition comprising a cycloaliphatic-based epoxy composition, which is particularly suitable for use as a structural adhesive in anchoring applications.

A hybrid system for use as an adhesive, coating or paint, wherein the hybrid system includes a) a reaction resin based on ,-unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a primary amine, and to related subject matter.

Use of a synthetic resin system as an adhesive for chemical fixing technology, especially for fixing anchoring means in drilled holes, which synthetic resin system includes a) a reaction resin based on , -unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a catalyst, and to related subject matter.

A method for installing fastener in a base material. The fastener has a shank having a first end and a second end defining a length, a head provided at the second end, and a thread provided on the shank which includes a leading edge and a trailing edge adapted remove portions of the base material when inserted into the base material. The method includes forming a hole having a diameter which is a nominal shank diameter of the fastener to be installed in the base material. The hole is then filled with an adhesive having a viscosity of 350 cP or less. Finally, the fastener is rotated into the hole such that the adhesive is forced into portions of the base material adjacent to the shank and thread when the thread is fully inserted into the hole.
