ADSORPTION CHARACTERISTICS OF SULPHONATED MELAMINE FORMALDEHYDE CONDENSATES BY HIGH PERFORMANCE SIZE EXCLUSION CHROMATOGRAPHY

This article describes an investigation into the adsorption characteristics of super plasticisers sulphonated naphthalene formaldehyde condensates (snfc) on cement particles. The cement used was cmf specification ordinary portland cement. High performance size exclusion chromatography has been used to measure the average molecular weight and molecular weight distribution of sulphonated melamine formaldehyde condensate admixtures. The method was then used to study the adsorption of these molecules on to the surfaces of cement particles. It was found that the molecules in the higher molecular weight fractions preferentially adsorbed on to the cement particles.
