In a process to produce a coated basic material for a hydraulic composition (11) in which the hydraulic composition is that of basic materials (14, 16) and water (15), the basic materials consist of several sub-groups (14, 16) and a hydraulic binding agent (14) brought together in a mixer. Prior to mixing the hydraulic composition, the basic materials (14, 16) are partly or completely mixed with an additive. Independent claims are also included for the following: (a) a coated basic material for the preparation of concrete; (b) an additive for concrete manufacture, and (c) a process to make the hydraulic composition. |
