摘要

Concrete ballast element (10) for a commercial vehicle, a construction machine, a crane or a mechanical construction, with at least one homogeneous concrete body (1) which has at least one exposed visible surface (2), the surface of the concrete body (1) at least in the area of the visible surface (2) is covered with a polyurea coating (3), characterized in that - the layer thickness is at least 1 mm; - that the concrete body (1) is interspersed with macro fibers (6) with a fiber length of at least 20 mm, the Macro fibers are formed from steel wire sections with a diameter of 0.5 mm to 1.5 mm, which are angled at least once in each end region; - that the coated surface has a three-dimensional structure and the coating (3) overlaps the visible surface (2) subsequent edges (4) and areas of curvature extends.
