ASTM C989/C989M-16

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: C989/C989M − 14 C989/C989M − 16
Standard Specification for
1
Slag Cement for Use in Concrete and Mortars
This standard is issued under the fixed designation C989/C989M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification covers slag cement for use as a cementitious material in concrete and mortar.
NOTE 1—The material described in this specification may be used for blending with portland cement to produce a cement meeting the requirements
of Specification C595/C595M or as a separate ingredient in concrete or mortar mixtures. The material may also be useful in a variety of special grouts
and mortars, and when used with an appropriate activator, as the principal cementitious material in some applications.
NOTE 2—Information on technical aspects of the use of the material described in this specification is contained in Appendix X1, Appendix X2, and
2
Appendix X3. More detailed information on that subject is contained in ACI 233R-03.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the
inch-pound units are shown in brackets. 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.
Values are stated in only SI units when inch-pound units are not used in practice.
1.3 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes
(excluding those in tables) shall not be considered as requirements of this standard.
1.4 The following safety hazards caveat pertains only to the test methods described in this specification. 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.
