Significance and Use

5.1 Rheological properties provide information about the workability of cementitious paste or mortar. This test method may be used to measure flowability of a cement paste or the influence of a specific material or combination of materials on flowability.

5.2 As rheological properties are sensitive to sample heterogeneities, special care is needed using this procedure so that sedimentation, particle migration away from the spindle or slippage at the surface of the spindle and container, is avoided.

Scope

1.1 This test method is used to measure the rheological properties such as plastic viscosity and yield stress of cementitious materials with particles up to 1 mm in diameter.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
