Effect of some prepared superplasticizers on the rheological properties of oil well cement slurries
Three superplasticizers namely: cyclohexanone glyoxylic sulfanilate (CGS), acetone glyoxylic sulfanilate (AGS) and melamine glyoxylic sulfanilate (MGS) were prepared and characterized using FT-IR.

Effect of superplasticizers with different molecular structures on fly ash-based geopolymer in early reaction stages [PDF]
The effectiveness of superplasticizers on the workability of fly ash-based geopolymer (FAG) pastes has been known to be far less obvious than in the case of cement pastes.

THE ROLE OF SOLVENT QUALITY AND OF COMPETITIVE ADSORPTION ON THE EFFICIENCY OF SUPERPLASTICIZERS IN ALKALI-ACTIVATED SLAG PASTES [PDF]
The loss of dispersing ability by polycarboxylates ether superplasticizers in alkali-activated slag cements has been widely reported. However, no clear-cut explanation of this phenomenon can be found to date. Therefore, the behaviour of poly(methacrylate-

Investigations on Stability of Polycarboxylate Superplasticizers in Alkaline Activators for Geopolymer Binders [PDF]
Calcined clays are interesting starting materials to be used as SCMs (supplementary cementitious materials) in cements or to be converted to geopolymers by activation with a high alkaline activator.

Hydrophilicity as a measure of the efficiency of the superplasticisers
This paper presents the results of chemical structural investigations of four new-generation superplasticizers (denoted here as SP-A through SP-M2) used in concrete production engineering. The commercial product samples, the gel permeation chromatography
