<p>In a hydraulic binder based on Portland cement clinker, care is taken that the maximum hemihydrate content does not exceed a certain maximum amount. A carbonate donor and at least one ironcomplexing compound are utilized as additives for regulating the properties of the binder. By controlling the hemihydrate content, it is possible to set the properties (workability, setting time, early and long-term strength) in a reproducible fashion. The binders according to the invention are distinguished by low sensitivity of the properties with respect to changes of the parameters (for example, water/cement ratio, processing temperature).</p> |
