Abstract
The mechanical properties of concrete reinforced by short dispersed steel fibres is recognized to depend as far as fibres are concerned on their volume fraction, slenderness and type. In experiments, it is pursued to disperse the fibres “randomly” through the mix. Analytical approaches to estimate mechanical properties are also based on “randomness”. Strict measures to prevent segregation and reorientation of the fibres cannot be taken in practice, however, so that deviations from the ideal state should be accounted for. Stereological principles are used for the development of structural models representing typical categories of non-random fibre dispersions approaching conditions met in practice. Such model concepts also allow for unbiased quantitative 3-D estimation of actual structural parameters by image analysis. Aspects of such an approach are discussed.
