Summary: | Presented and described is a method for manufacturing concrete elements having at least one concrete layer, wherein concrete for at least one element is introduced into a mould, the concrete is compacted by vibration and/or by tamping and subsequently cures, wherein to the concrete layer, prior to compaction, at least one portion of a granular material is applied by means of an application device, where the concrete introduced into the mould has a water/binder (w/b) ratio of 0.30 to 0.50 prior to curing and where as granular material a material is used comprising (a) a scatter component having an average particle diameter of 0.1 to 5 mm in an amount of 65 to 95 wt % and (b) binder in an amount of 5 to 35 wt %, based in each case on the overall composition of the granular material. |
