Title: Effects of Superplasticizers, Powder Fineness, and Solution Electrolyte Content on the Rheology of Model Paste Systems
Author(s): D. S. Swift and P. F G. Banfill
Publication: Special Publication
Appears on pages(s): 499-512
Keywords: ground granulated blastfurnace slag; lignosulfonate; magnesium oxide; polycarboxylate; rheology
Abstract:Model hydraulically inactive powders have been used to investigate the effect of polycarboxylate and lignosulfonate superplasticizers. A new rotational rheometer, avoiding the risks of sample separation, slippage and uncertain shear history, was used. Magnesium oxide can be used to model the rheology of cement pastes but an appropriate solution electrolyte composition must be used. Ground granulated blastfurnace slag can be used but results are sensitive to glass content and particle fineness. The effects of admixture chemistry can be studied using model paste systems.
