Observation of steel fibres in concrete with Computed Tomography
HighlightsLonger mixing time but resulted higher residual flexural-tensile strength values.Highest amount at the bottom and lowest amount of fibres were observed at the top.Average distribution of steel fibres was more homogeneous with 30min mixing time.Fibre orientation has been clearly indicated by CT.
AbstractNowadays application of fibre reinforced concretes (FRC) becomes more and more widespread, due to the favourable experiences with their behaviour. As a consequence, an increasing number of studies are published on different aspects of FRC. Several scientific papers indicate the importance of homogeneous distribution of fibres. Our study includes an important step towards the analysis of fibre distribution and fibre orientation with Computed Tomography (CT).In our experimental study effects of different parameters of mixing on the characteristics of FRC are also included. Effect of mixing time and amount of fibres on the post-cracking residual flexural and compressive strengths, orientation and distribution of fibres are discussed.
