摘要：

In the present work the thixotropic behaviour of fresh Portland cement pastes is examined on the basis of the stress transients determined at constant shear rate. Some significant quantities are considered: the difference between maximum and equilibrium shear stresses, the breakdown area and the density of the energy absorbed by thē material for the breakdown of the thixotropic structure. A distance parameter is proposed in order to evaluate the influence of the specific surface and water/cement ratio on these quantities. © 1979.
