ABSTRACT
Fundamental interactions between polymeric superplasticizers and cement were studied. Cements with different alite-, belite-, C3A- and C4AF-contents were used. The use of commercially available superplasticizers like melamine formaldehyde sulfite- (MFS) and â-naphthalene sulfonic acid formaldehyde-(NSF) resins was investigated. These superplasticizers (industrial products) were characterized with the help of their molecular weights and polymeric radii, as well as by estimation of the anionic charge density in water and in the cement filtrate of four CEM I cements. Application data of the eight cement-superplasticizer-combinations (heat flow calorimetry and mini-slump tests) were obtained and the surface chemistry of the superplasticizers with cement (zeta potentials and superplasticizer adsorption on cement) was studied.
