ASTM C 1645/C 1645M – 09 Standard Test Method for Freeze-thaw and De-icing Salt Durability of Solid Concrete Interlocking Paving Units1
Author: ASTM Committee C27 | Size: 0.1 MB | Format: PDF | Publisher: ASTM | Year: 2009 | pages: 3
1.1 This test method evaluates the resistance to freezing and
thawing of solid interlocking concrete paving units conforming
to the dimensional requirements of Specification C 936/
C 936M. Units are tested in a test solution that is either tap
water or 3 % saline solution, depending on the intended use of
the units in actual service.
1.2 The values stated in either SI units or inch-pound units
are to be regarded separately as standard. The values stated in
each system may not be exact equivalents; therefore, each
system shall be used independently of the other. Combining
values from the two systems may result in non-conformance
with the standard.
1.3 This standard does not purport to address all of the
safety concerns, in any, associated with its use. It is the
responsibility of the use of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitation prior to use.
