Title: Estimation of Effects of the Specific Properies of Particles on the Viscosities of Cement Pastes
Author(s): K. Hattori and K. lzumi
Publication: Special Publication
Appears on pages(s): 511-536
Keywords: Cement pastes; rheological properties; viscosity
Abstract:Very little has been known about the relationship between the specific properties of particles and the viscosity of suspensions containing them, although it seems very important for the reliable design of quality in the actual use. After the introduction of new rheological theory by Hattori and Izumi (HI theory) based on the DLVO theory and on the structural viscosity theory, it became possible to estimate the time-dependent viscosity of suspension either agitated or unagitated by the calculation. Based on the HI theory, the time-dependent viscosity of unagitated cement paste,-for which the completely dispersed state was assumed as the initial condition, was calculated and results of calculations for the estimation of viscosity increase of cement pastes are presented by the curves showing effects of various properties of cement powders and the condition of use.
