Viscosity modifying agents (VMAs) are essential ingredients for the production of flowable cement-based materials. This paper presents an overview of commonly used VMAs and attempts to shed some light on the underlying physics at the origin of their mechanisms of action.
Utilization of polysaccharides as viscosity modifying agent …
However, to avoid the segregation of concrete, either the fine material content should be increased, or a viscosity modifying agent (VMA) should be used. In this study, the possibility of producing self-compacting concrete with a lesser amount of fine material than the conventional SCC while using a polysaccharide type VMA is investigated.
Using CaO as a modifier agent to optimize the pore …
Using CaO as a modifying agent greatly optimized the microstructure and physical properties of ed ceramics that were prepared using granite scrap as a raw material and SiC as a ing agent. The results of this work show that the appropriate amount of CaO can reduce the viscosity of the melt to balance the expansion drive of the …

Working mechanism of viscosity-modifying admixtures
Regarding the impact of water retention agents on the yield stress, contradictory results have been found in the literature. Some authors confirm that cellulose derivative (CE) admixtures slightly decrease the yield stress (Patural et al., 2011, Hossain and Lachemi, 2006).Patural et al. (2012) explained this decrease in base of the steric …
