Certification of SRM 2492: Bingham Paste Mixture for Rheological Measurements
As measurements with rheometers can involve flow in a complex geometry, it is important that they are calibrated with a standard reference material (SRM). NIST has produced a Standard Reference material for paste (SRM 2492) as the first step for the development of a reference material for concrete rheometers. The process used to develop both the SRM 2492 and the mortar reference material is presented, including measurements, statistical analyses, and modeling. The developed SRM consists of a mixture of two components, corn syrup and fine limestone and has the texture of cement paste.

Influence of Mineral Admixtures on the Rheology of Cement Paste and Concrete
Rheological tests on cement paste were used to successfully select the type and dosage of mineral admixtures that improved concrete workability. Among the six different mineral admixtures tested, the ultra fine fly ash was determined to give the best results by reducing the yield stress and viscosity.

Rheological Nomenclature
A guide to the nomenclature in rheology and rheometric measurements. It has been written particularly for use in ceramic sciences and provides definitions of terms and expressions relating to the measurement of rheological properties in liquid-based particulate systems (suspensions, pastes and gels).

Modified Slump Test to Measure Rheological Parameters of Fresh Concrete
The ease of placement of concrete depends upon at least two physical properties, the yield stress and plastic viscosity. Currently the most common field test is the slump test, and it is related only to the yield stress. Therefore, a simple field test method intended to provide an evaluation of the two Bingham rheological parameters, yield stress and plastic viscosity, was developed. To determine the plastic viscosity the time necessary for the upper surface of the concrete in the standard slump cone to slump 100 mm was measured. The apparatus and test procedure are described.

Comparison of Concrete Rheometers
Comparison of measurements from five types of concrete rheometers (four of them are commercial available). The aim was to provide data to establish correlations among them. The Rheometers are named: BML (Island), BTRHEOM (France), CEMAGREF-IMG coaxial rheometer (France), IBB (Canada), Two-Point (UK).
