Procedure for fabrication of reinforcement elements for concrete, where an extended, preferably continuously fiber bundle (10), especially of carbon fibers, impregnates (3) by a matrix of a plastic material followed by curing. The fiber bundle (10), including a significant amount of single fibers, is brought after impregnation (3) and prior to curing (17) to cooperate with a particle shaped material (15), preferably sand, as adhere to the fiber bundle surface mainly without coming in between the fibers and fixate to the surface by curing, for creation of a reinforcement element.
