“…The failures of adhesive anchors are in general influenced by many factors, which can be marked as installation factors, service factors or factors directly influenced by material characteristics [1,[10][11][12][20][21][22][23]. The main installation factors are mainly: anchor diameter, embedment depth, the drilling procedure and type of the drill, installation temperature, moisture condition and the drilled hole's orientation.…”

The analysis presented in this paper is focused on problems of bond strength as an overall bond quality parameter of industrial adhesives for structural anchoring. In the first part, the problem of bond strength as the most important parameter influencing the final anchor resistance to tension load is described. Further in the text, a new methodology of simplified testing of the strength parameters of adhesives is described. Special test specimens made from steel are repeatedly used in this methodology. Additionally, results of these tests on some new recipes for adhesive are presented. Especially, epoxy resins with special fillers, such as carbon fibres, carbon nanotubes or graphene, were tested. The use of these adhesives in temperatures close to zero degrees Celsius was also tested.

“…While there is evidence that the addition of steel fibre to concrete can provide a beneficial impact on anchor performance (see, e.g. [3]; [4]), testing of SFRSSC is not known by the authors. The anchor type investigated here, a Hilti HUS3 screw anchor, has a known performance when embedded in traditional concrete (without fibres), as documented in the European Technical Assessment [5].…”

Industrial concrete warehouse slabs constructed with steel fibre reinforced self-stressing concrete (SFRSSC),with a moderate to high content ( ≥ 30 kg•m -3 ) of steel fibre reinforcement and expansive cementitious additives, can provide equivalent load bearing capacity as traditional reinforced or unreinforced concrete slabs with a reduced slab thickness. The reduction in slab thickness is possible due to improved flexural capacity of SRFSSC together with a reduced propensity for cracking and curling, common issues in traditional concrete slabs, caused by shrinkage. By reducing the slab thickness, the allowable length of mechanical anchors, commonly embedded in concrete slabs to restrain the racking system, is impacted. Anchors,and accompanying design aids and guidance provided by anchor manufacturers, available in the market are generally produced with traditional concrete slabs with higher thickness in mind. There is generally a lack of guidance and design aids for applications with thinner slabs constructed with SFRSSC. This paper presents data from over 250 pull-out test results of screw-type anchors extracted from SFRSSC slab specimen. The test series varies parameters from both the screws (diameter and length) and the SFRSSC slabs (slab thickness, fibre type/content, and concrete compressive strength). Testing was completed in accordance with relevant European Assessment Documents and results conclude combinations of anchor type and slab details (thickness, fibre type/content, and concrete compressive strength), where equivalent or improved tensile capacity is achieved for screw anchors embedded in SFRSSC.

Post‐installed fastening systems are essential in structural engineering nowadays. Triggered by the increasing popularity of high strength concrete (HSC) and ultra‐high performance concrete (UHPC), fastening in these basements is more and more frequently applied. This inevitably leads to the question of the applicability of conventional fastening systems and the corresponding design concepts with concrete showing a compressive strength of up to 200 N/mm2. According to EAD 330232‐00‐0601, mechanical fasteners have to be placed in predrilled holes in compacted reinforced or unreinforced concrete without fibers with strength classes in the range of C20/25 to C50/60 in compliance with EN 206. This means that concrete strength class C50/60 also provides the reference for higher concrete strength; the impact of fibers and accompanying increase of concrete ductility is also excluded. Within the framework of this contribution it is intended to analyze the following aspects: (a) proof of applicability of various fastening systems in unreinforced and fiber‐reinforced high strength concrete via experimental investigations and (b) making a statement regarding the currently valid European Assessment Document and provide experimental background for this issue.
