Two industrial polycarboxylate superplasticizer samples have been selected to be used within the Priority Program 2005 of the German Research Foundation (
DFG
SPP 2005). The
PCE
polymers were characterized via Size Exclusion Chromatography (SEC) to determine their molar masses (
M
w
, M
n
), the polydispersity index (PDI) and the conversion rate which indicates the incorporation of the macromonomer into the polymer. The anionic charge amount of the
PCE
samples was assessed via charge titration employing a cationic polymer. Furthermore, the cement dispersing properties of the
PCE
polymers were captured via 'mini slump' tests so as to assess their ability to fluidize CEM I 42.5 R and CEM III/A 42.5 N samples, respectively. Also, interaction between the PCEs and the surface of the cements was investigated via adsorption and zeta potential measurements of aqueous cement suspensions. The results shall be used for the ongoing research within the Priority Program.
