摘要：
A study of the behavior of fresh cement pastes under shear in a rotational viscometer of the Rheotest-2 type, especially designed for this purpose, is described. It is shown that an addition of fly ash to Portland clinker influences the change of flow behavior of cement pastes from thixotropic flow to thixotropic-dilatant flow. Moreover, introduction of fly ashes without decreasing the amount of cement brings about an increase in the basic rheological characteristics of cement pastes, growth intensity being dependent on volume fraction of solid and percentage of addition.
