2021-7-27 · The aqueous phase of a cement slurry contains ionic species and organic additives. Therefore, the rheological properties of the aqueous phase can differ greatly from those of water, notably when high-molecular-weight water-soluble polymers (e.g., Cement fluid-loss control agents) are added. The viscosity of the interstitial fluid can also vary significantly with temperature.

Rheological properties of concentrated aqueous

However, when used as an injectable biomaterial, CPC slurry is a concentrated aqueous suspension, since the content of powder in the slurry is more than 60% (powder-to-liquid ratio, P/L>1.75), with the rheological behavior being more complex than the normal suspension. Moreover, CPC slurry is a reactive system, and goes through a continuous transformation from a fluid to a solid state, and its
