Abstract:
A method of separating different constituents of a fine fraction that is produced in a prior method for separating a concrete for deconstruction. The method allows the reuse of these different constituents in the production of a new cement and/or of a new concrete, the fine fraction including sand and at least 30% by mass of hydrated cement paste.
