Cement - Superplasticizer Compatibility - The Concrete

Compatibility between cements and superplasticizers is affected by a combination of reasons, including cement composition, admixture type and dosage, concrete mixture proportions etc. Aïtcin [1998] describes the complicated nature of the interaction using the schematic diagram shown in Figure 2.

Cement/Superplasticizer/Air-Entraining Agent Compatibility

Sep 01, 1994  Since mixed results have been reported when superplasticizer is added to air-entrained concrete at the jobsite, a research program was undertaken to study the compatibility between three air-entraining agents, four water reducers, and one polynaphthalene sulfonate superplasticizer currently used in Eastern Canada.

Compatibility of Polycarboxylate Superplasticizers with ...

Sep 01, 2003  The low alkali cement shows lower sensitivity to differences in structure of polycarboxylate superplasticizers than cements with higher alkali content. The adsorption of polycarboxylate polymers on cement is driven by the structural features of the polymer and can be directly related with the flow of the cement paste.
