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

โฆ Synopsis
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 Rotovisko-Haake RV3 and RVll were employed. The cement pastes were prepared from a Portland cement 324. The water/cement ratio was within the range 0.30 รท 0.40.

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
