Standard Test Method for Bleed Stability of Cementitious Post-Tensioning Tendon Grout

2018-10-24 /Active
Significance and Use:

4.1 This test method is designed to evaluate the bleed stability of a freshly-mixed grout under static pressure. It can be used in both the laboratory to qualify grout materials and in the field as a quality control test. When used to qualify grout materials, replicate tests may be specified. It is intended that the test pressure, acceptance criteria, and number of replicate tests be set forth in the contract documents if this test method is referenced. These values will normally vary depending on the vertical rise of the post-tensioning tendon.

Note 1: Appendix X1 includes a reference for an example of test pressures and bleeding limits.

4.2 The procedure for this test was developed by Schokker et al.4 based on previous work by Schupack.5


1.1 This test method is designed to determine the bleed stability of freshly-mixed cementitious grout under static pressure.

1.2 Units—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 and health practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)

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.
