ASTM A 944 Document Information:
Title
Standard Test Method for Comparing Bond Strength of Steel Reinforcing Bars to Concrete Using Beam-End Specimens
ASTM International
Publication Date:
Oct 1, 2005
Scope:
(Footnote *)
This test method describes procedures to establish the relative bond
strength of steel reinforcing
bars in concrete.
This test method is intended to determine the effects of surface
preparation or condition (such as
bar coatings) on the bond strength of deformed steel reinforcing bars
(of sizes ranging from No. 10
to No. 36 [No. 3 to No. 11]) to concrete.
The bond strengths obtained using this test method are not directly
applicable to the design of
reinforced concrete members.
NOTE 1 - The bond strengths obtained using this test method are
generally higher than obtained in
development or splice tests using beams with the same embedment
lengths. The results obtained using
this test method should only be used for comparisons with results for
other reinforcing bars tested
using this method.
The values stated in SI units are to be regarded as the standard. The
values given in brackets 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.
Footnote * - A Summary of Changes section appears at the end of this
standard.
