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

Importancia y uso:

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
