METHOD FOR PRODUCING A COATED BASIC MATERIAL FOR A HYDRAULIC COMPOSITION, COATED BASIC MATERIAL FOR A HYDRAULIC COMPOSITION ADDITIVE FOR A HYDRAULIC COMPOSITION AND METHOD FOR PRODUCING A HYDRAULIC COMPOSITION
: The invention relates to a method for producing a coated basic material for a hydraulic composition (11) comprising a basic material (14, 16) and water (15). According to 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 composition the basic material (14, 16) and the water (15) are mixed in a mixer (8). Prior to the mixing of the hydraulic composition, the basic material (14, 16) is at least partially coated with an additive (13). The invention also relates to a coated basic material to be used in concrete production, to an additive for concrete production and to a method for producing a hydraulic composition.
