The invention relates to a method for producing a coated basic material for a hydrauliccomposition (11) comprising a basic material (14, 16) and water (15). Accordingto the invention, the basic material can consist of several sub-groups (14, 16)and at least one hydraulic binding agent (14) and to produce the hydraulic compositionthe basic material (14, 16) and the water (15) are mixed in a mixer (8). Prior tothe mixing of the hydraulic composition, the basic material (14, 16) is at leastpartially coated with an additive (13). The invention also relates to a coatedbasic material to be used in concrete production, to an additive for concreteproduction and to a method for producing a hydraulic composition. |
