An experimental preparation of fibre concrete to software's detection of fibres

摘要

Fibre concrete requirements are only met if the fibres in its volume are evenly distributed.Their direction and orientation should be equal around each axis in a three-dimensional space.The requirement is that the fibres to be evaluated in the final hardened fibre concrete are cut from fibre concrete sections.Homogeneity can also be verified on fibre-concrete cross-sections.Fibre Position Evaluation is a mathematical task that is not presented here but is currently made up of the results of this experiment.In the first step, it was necessary to prepare samples to obtain the necessary cross-sections.In the next step, it was necessary to create conditions by creating a contrast between the fibres and the concrete to create software capable of detecting fibres.In this paper, the principle of detection of fibres based on the detection of cut section images is described.There are several methods used to highlight the concrete matrix over the fibres.Also presented are the results of adding and detecting fibres.
