Maria Vega Cañamares, Santiago Sanchez-Cortes and Sagrario Martinez-Ramirez Structural characterization of a third-generation commercial cement superplasticizer by Raman spectroscopy and DFT calculations Journal of Raman Spectroscopy 43
The structure of an unknown polycarboxylate based cement superplasticizer was determined by the comparison of the experimental FT-Raman and the density functional theory calculated spectra. Different models based on polycarboxylates were proposed. The final structure was the one of a polycarboxylic acid.
