摘要

尽管在实际使用中对可靠的质量设计似乎非常重要,但人们对颗粒的特定性质与含有它们的悬浮液粘度之间的关系知之甚少。Hattori和Izumi在DLVO理论和结构粘度理论的基础上引入了新的流变理论(HI理论)后,通过计算来估计搅拌或未搅拌悬浮液的随时间变化的粘度成为可能。以HI理论为基础,以完全分散状态为初始条件,计算了未搅拌水泥浆体粘度随时间的变化规律,并通过水泥粉的各种性能和使用条件的影响曲线给出了水泥浆体粘度增量估计的计算结果。

Estimation of Effects of the Specific Properies of Particles on the Viscosities of Cement Pastes
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.
