【 摘 要 】

In this paper the influence of the boundary conditions on the fibre orientation distribution in rheology simulations of the casting of steel fibre reinforced concrete is discussed. The slip-length of the boundary condition can have a significant influence on the orientation of the fibres. This means that the material and surface properties of the formwork need to be taken into account when designing the casting technology for elements made of steel fibre reinforced concrete. This also implies that there is a chance to influence the fibre orientations by choosing appropriate surface properties of the formwork.
