Abstract (en)
[origin: EP1510314A2] Production of multicolored concrete blocks comprises filling colored concrete mortar from a silo into a first receiving chamber (10) of a filling truck (5), transporting the filling truck until it lies above a molding tool for the concrete blocks, and filling the molding tool with the concrete mortar from the filling truck. Afterwards the filling truck is removed and the concrete mortar is compacted. A different colored concrete mortar filled into at least one additional receiving chamber (11) of the filling truck is placed in the molding tool on top of the first concrete mortar using at least one rotating distributor roller (12) extending perpendicularly to the path of the filling truck. An independent claim is also included for a device used in the production of multicolored concrete slabs.
