provisions:
1. All references to the ASTM Standards contained in ASTM C 685/C 685M-07 shall be replaced with the corresponding AASHTO Standard.
2. Section 6 (Ordering Information), Section 11 (Strength), and Section 12 (Failure To Meet
Strength Requirements) are excluded.
3. The Table 2 contained in this standard shall be used in lieu of Table 2 of ASTM C 685/C 685M-07.
1. Scope
1.1 This specification covers concrete made from materials
continuously batched by volume, mixed in a continuous mixer,
and delivered to the purchaser in a freshly mixed and unhardened
state as hereinafter specified. Requirements for quality of
concrete shall be either as hereinafter specified or as specified
by the purchaser. When the requirements of the purchaser differ
from this specification, the purchaser's specification shall
govern. This specification does not cover the placement,
consolidation, finishing, curing, or protection of the concrete
after delivery to the purchaser. Tests and criteria for batching
accuracy and mixing efficiency are specified herein.
1.2 The values stated in either SI units, shown in brackets,
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 nonconformance
with the standard.
1.3 This specification references notes and footnotes which
provide explanatory material. These notes and footnotes (excluding
those in tables and figures) shall not be considered as
requirements of this specification.
1.4 This standard does not purport to address all 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. (Warning--Fresh hydraulic cementitious
mixtures are caustic and may cause chemical burns to
skin and tissue upon prolonged use.2)
