Standard Test Method for Evaluating Bond Strength for 0.600-in. [15.24-mm] Diameter Seven-Wire Steel Strand, Grade 270 [1860], Used in Prestressed Ground Anchors

Importancia y uso:

4.1 Seven-wire steel strand is used in pre-tensioned and post-tensioned concrete construction.

4.2 0.600 in. [15.24 mm] diameter, Grade 270 seven-wire steel strand is used to make prestressed ground anchors which are often bonded to cement grout.

4.3 Manufacturing processes, subsequent handling, and storage conditions may influence the strand bond.

4.4 The primary use of this test method is to establish the relative bond strength of 0.600 in. [15.24 mm] seven-wire steel strand.

4.5 The relative bond strength is determined by recording the pullout force at a certain displacement of the strand.
