2014-9-2 This paper presents the findings of an investigation of the fiber content variations in concrete being discharged from a ready-mix truck at the construction site. Concrete samples were extracted from the truck drums at the beginning, middle and end of discharge. Subsequently, fibers in each sample were separated from the concrete, and weighed.

SHORT FIBERS DISTRIBUTION INVESTIGATION IN FIBER CONCRETE stresses in material. In the present investigation SFRHSCcasting was modeled as filling the mould by viscous flow. Simultaneously single steel fiber rotation and motion in the flow with internal velo-city gradients were investigated experimentally and numerically (using FEM).

In this context, the aim of this study is to investigate the spatial distribution of steel fibers, as well as of porosity in reinforced concrete samples. To this end, we used a microtomography system calibrated to operate at a voltage of 80 kV, electric current of 100 μA and a pixel size equal to 24 µm.
