    Abstract

    This dissertation seeks to assess a new development within the reinforcement sector, especially the pull out behaviour of a newly developed steel fibre. The investigation was carried out to gain a deeper understanding of the newly developed hooked end steel fibre under tension. Therefore, different concrete mixes were used to determine the influence of the water-cement ratio as well as silica fume as a cement replacement. The water cement-ratios were set to 0.25, 0.35 and 0.45. Further, the high range water reducing admixture superplasticizer was used to create a favourable workability of the concrete. The workability was measured via a slump test and the aim was a slump of 100 mm to 200 mm. The steel fibre was 50% embedded within cubes with an edge length of 50 mm. In addition, the silica fume contents were set to 0%, 5%, 10% and 15%. The sampling also included concrete cubes without fibres. The cubes had an edge length of 100 mm in order to determine the validity of the mixes via compressive strength tests. The overall number of samples for this investigation was 72 samples for the pull out test and 72 samples for the compression test.
