摘要

Concrete with the addition of fibres is increasingly being used in the construction industry instead of the usual steel bar reinforcement. In the meantime, intensive research work and investigations have led to a sound knowledge of the material characteristics. This makes it possible to assess the advantages and disadvantages of this innovative building material in terms of practical and economic construction. Compared to reinforced concrete, however, this area is still under-researched; particularly with regard to the load-bearing behaviour of fasteners in fibre-reinforced concrete, science is still lagging behind, and anchor certifications for this relatively new building material as an anchoring base are not adequately defined. In order to investigate the question of whether and how the addition of fibres to normal concrete improves the load-bearing capacity of fasteners, axial tensile tests were carried out on product-neutral headed stud anchors. The results should provide new knowledge in this field of research. For this work, fasteners were tested in polymer fibre concretes with different mix designs and different fibre contents and compared to a standard plain concrete.
