Abstract
The invention relates to the preparation of mortars and concretes in the presence of a water-reducing plasticizer. The plasticizer used is a surface-active compound containing at least one perfluoro group and at least one ionic or nonionic hydrophilic group. It is possible for these groups to be linked directly or via one or more divalent chain links.
