Characterization data of reference industrial polycarboxylate superplasticizer VP 2020/15.2 used for Priority Program DFG SPP 2005 “Opus Fluidum Futurum - Rheology of reactive, multiscale, multiphase construction materials”

An industrial polycarboxylate superplasticizer sample has been chosen to be used in the Priority Program 2005 of the German Research Foundation (DFG SPP 2005). The molecular properties such as molar masses (Mw, Mn), polydispersity index (PDI) and macromononmer conversion rate of this superplasticizer sample were determined via Size Exclusion Chromatography (SEC) and its specific anionic charge amount was obtained via charge titration. Furthermore, the dispersing effectiveness of this superplasticizer sample was assessed through ‘min-slump’ tests in pure OPC (CEM I 42.5 R) and in a limestone-calcined clay (LCC) cement. Moreover, adsorption of the superplasticizer on both cements and dosage-dependent development of the zeta potential of the cement suspensions were captured. The data shall be used for the ongoing research within the Priority Program.
