✦ Synopsis

The theology of fresh cement pastes is difficult to obtain and data is often difficult to reproduce. Factors involving mixing, testing techniques, test geometries, etc contribute to the measurement problems. This review addresses these problems and comments on the analysis of experimental data. This review covers the large body of information published in recent years on the characteristics of fresh cement pastes. The detennination of the theological properties of cement slurries is an important step in the complete characterization of cements. Knowledge of the flow properties is important in a number of industries which use cements. For instance, the oH industry requires a good understanding of cement slurries in order to properly evaluate the displacement and flow rates (required to achieve optimum mud removal) for optimum cement placement. In other uses, dense, impermeable, hardened cement composites are important for applications requiring high performance. To achieve such composites, mixing and consolidation parameters must be investigated, which includes an understanding of the behavior of cement mixtures in the plastic or fresh state.
