摘要: The rheological properties of fresh cement paste are highly influenced by a large number parameters, among which the most important factors applied shear stress, and history, age sample temperature. effects these parameters on yield stress (designated as structural limit in this work), viscosity recovery rate (i.e., change dynamic with time at rest) were studied. In parallel, changes ion composition carrier liquid, mineral phase content granulometry investigated. results reveal that all investigated exhibit an approximated bi-linear trend respect to degree hydration, period quasi-constant until hydration approximately 0.07, followed non-linear increase. This increase could be attributed formation calcium hydroxide (CH) calcium-silicate-hydrate (C-S-H) via calorimetry results. With regard effect history properties, showed minor dependency immediately after end shearing, which, however, vanished within first minute rest. same is true for rate. presented give detailed insights into influences properties-especially thixotropy-of pastes.
