Use of Non-Purified Polycarboxylate Ether (PCE) as Superplasticizer - Structural Determination and PCE/Cement Interaction

Abstract: The aim of this paper is to investigate the interactions between industrial-grade polycarboxylate ether (PCE) polymers and ordinary Portland cement to assess whether it is possible to draw structure/performance relations for impure, yet fully characterized, poly-mers. To this end, thirteen PCE polymers were synthesised in industrial fashion, deeply ana-lyzed and tested in cement paste. Chemical stability and adsorption behaviour have been evaluated through gel permeation chromatography technique, leading to in… Show more
