Impact of plasticizers’ types on the performance of calcium aluminate cement
Journal of Materials Research and Technology, 2022 Nowadays it is almost impossible to design a cement-based mixture without the application of some plasticizing additives. There have been developed many types of plasticizers, but they are mostly directed for Portland cement applications.

ce/papers, Volume 6, Issue 6, Page 290-296, December 2023., 2023 Abstract It was analysed how a low Na5P3O10 (STPP) concentration influences the hydration of a calcium aluminate cement. It is known that the hydration of a CAC‐Calcite system precipitates C2AHX as a precursor phase at 23°C during hydration before the formation of hemi‐ or monocarbonate and the additional formation of CAH10 and AH3.
