Technical description of the product
The subject of this European Technical Assessment is the post-installed connection, by
anchoring or overlap connection joint, of reinforcing bars (rebars) in existing structures made of
normal weight concrete, using the "Injection system TEKNOBOND 401EP for rebar connection"
in accordance with the regulations for reinforced concrete construction.
Reinforcing bars made of steel with a diameter φ from 8 to 40 mm or the tension anchor ZA of
sizes M12 to M24 according to Annex A and injection mortar TEKNOBOND 401EP are used for
rebar connections. The rebar is placed into a drilled hole filled with injection mortar and is
anchored via the bond between rebar, injection mortar and concrete.
The product description is given in Annex A.

General information
Tekno Yapi Kimyasallari SAN. TIC. A.S. authorized the evaluation of the fire resistance
of the chemical anchor system TEKNOBOND 401EP for axial tension and shear loads.
The evaluation is based on tests that were conducted by the Technical University Kaiserslautern under fire exposure according to DIN EN 1363-1:2012 [2] and Technical Report TR 020 [1]. The test results are summarized in test report 17061MR15557 [3].
This evaluation provides fire resistances which covers anchors with fire attack from one
side only.

Product description
The Injection system TEKNOBOND 401EP adhesive is a bonded anchor system consisting of a plastic cartridge containing the injection mortar and a steel part.
The injection system Tekno Yapi Kimyasallari SAN. TIC. A.S. is designed for the use in
concrete according to the European Technical Assessment ETA-22/0362 [6].

Scope of evaluation
The present evaluation of fire resistance for Injection system TEKNOBOND 401EP anchor systems in concrete is assessed with respect to its fire resistance properties as anchor applications in walls and ceilings. The tests which this evaluation refers to, are executed with vertical arranged anchors and axial load application. Furthermore, the anchors
were exposed to the standard temperature-time curve (ETK) [2]. In the tests a fixture
according to TR020 was used, therefore the following fire resistances cover only anchors
protected from fire by attachments similar to the fixture according to TR020 [1].
The assessment of steel failure and concrete cone failure is carried out in dependence
on TR020 [1]. Additionally the failure type pullout failure is assessed as explained in below.
a. Steel failure:
Steel failure is assessed according to TR020 [1]. In some cases more than one anchor
size is assessed together
b. Pullout failure:
Pullout failure is assessed by the current state of scientific knowledge according to the
research report “Qualfikation von Verbunddübeln im Brandfall” [7] A combination of thermal simulation and assessment of test results was used.
c. Concrete cone failure:
Concrete cone failure is assessed according to TR020 [1].
For internally threaded rods steel failure has to be proven with using the internal thread
diameter. The outer diameter of the internally threaded rods can be used to verify the
pullout capacity.

The test results according test report 17061MR15557_2 [3] shows no significant reduction between cracked and non-cracked concrete. However a reduction factor between
cracked and non-cracked concrete of 0,75 was considered.

Summary
The listed fire resistances are valid for single anchors with an edge distance of more than
ccr=2 hef and a spacing to the adjacent anchor of s= 2 ccr= 4 hef. Edge and spacing distances have to be chosen so that steel – or pullout failure are decisive.
