ASTM A981-97-Reapproved2007

Historical Standard: Standard Test Method for Evaluating Bond Strength for 15.2 mm (0.6 in.) Diameter Prestressing Steel Strand, Grade 270, Uncoated, Used in Prestressed Ground Anchors

ASTM A981

Scope

1.1 This test method describes procedures to establish the relative bond strength of 15.2 mm (0.6 in.) diameter, Grade 270 prestressing steel strand in cement grout as used in prestressed ground anchors for the purpose of evaluating the effects of manufacturing practices on bond strength.

1.2 The bond strength values obtained shall not be used to design the bond length of ground anchors that depend on field conditions.

1.3 This test method is not intended to be used as a bond test for pretensioned concrete applications.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
