A controlled stress rheometer has been used to determine the creep and recovery behavior of flocculated cement pastes. The behavior was found to depend on the level of applied stress. At a lower applied stress, the creep curve of each paste was characteristic of a nonlinear viscoelastic solid, with

An investigation on the rheological behavior of fresh cement pastes is reported. In particular, the results obtained by the application of various experimental procedures and measurement devices with different geometric characteristics are compared and discussed. The coaxial cylinder viscometers Rot
Fresh cement slurries typical of those used in the oil industry during drilling operations are assessed for the growth of structure in the first few hours after mixing by the use of shear modulus and ultrasonic pulse velocity measurements. It is shown that during the first two hours, the shear modul
