Paste fluidity of two-component cement dispersant formulation - Another additivity rule

Chun, B.W.

Ultrafiltered lignosulfonate (UF-LS), PEO comb-shaped polycarboxylate (PC), and gluconic acid (GA) are formulated with varied ratio, and their dispersion ability is tested in cement paste. While PC and GA formulation follows an ordinary paste flow value additivity (dose-response additivity), UF-LS and PC formulation obeys the additivity in terms of its required dosage for a given paste flow (required dose additivity). The observed required dosage additivity rule may help us further understand cement and multiple-component dispersant interaction.
