Scope of Specification1.1 This specification covers ready-mixed concrete manufactured and delivered
to a 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. In any case where the requirements of the
purchaser differ from these in this specification, the purchaser's specification
shall govern. This specification does not cover the placement, consolidation,
curing, or protection of the concrete after delivery to the purchaser.
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
non-conformance with the standard.
1.3 As used throughout this specification the manufacturer produces
ready-mixed concrete. The purchaser buys ready-mixed concrete.
1.4 The text of this standard 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 the standard.
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.
