1、Designation:C989/C989M11 Designation: C989/C989M 12Standard Specification forSlag Cement for Use in Concrete and Mortars1This standard is issued under the fixed designation C989/C989M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision
2、, 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 Department of Defense.1. Scope*1.1 This specification cov
3、ers three strength grades of slag cement for use as a cementitious material in concrete and mortar.NOTE 1The material described in this specification may be used for blending with portland cement to produce a cement meeting the requirementsof Specification C595 or as a separate ingredient in concret
4、e 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 2Information on technical aspects of the use of the material described in this specification
5、is contained in Appendix X1, Appendix X2, andAppendix X3. More detailed information on that subject is contained in ACI 233R-03.21.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, theinch-pound units are shown in brackets. The val
6、ues stated in each system may not be exact equivalents; therefore, each system shallbe 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 foll
7、owing safety hazards caveat pertains only to the test methods described in this specification. This standard does notpurport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard toestablish appropriate safety and health practic
8、es and determine the applicability of regulatory limitations prior to use.1.4 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.2. Referenced Doc

Ordering Information5.1 The purchaser shall specify the grade of slag cement desired and the optional chemical or physical data to be reported.6. Additions6.1 Slag cement covered by this specific
19、ation shall contain no additions except as follows:6.1.1 It is permissible to add calcium sulfate to slag cement provided it has been demonstrated by Test Method C1038 that atest mixture will not develop expansion in water exceeding 0.020 % at 14 days. In the test mixture, 50 % of the mass of portla
20、ndcement shall be replaced by an equal mass of slag cement. The portland cement used in the test mixture shall meet the requirementsof Specification C150. When the manufacturer supplies cement under this provision, upon request, supporting data shall besupplied to the purchaser.6.1.2 When processing
21、 additions are used in the manufacture of slag cement, the maximum amount used shall comply with therequirements of Specification C465 when tested using a blend that is 50 % slag cement and 50 % portland cement by mass.7. Chemical Composition7.1 Slag cement shall conform to the chemical requirements
22、 prescribed in Table 2.8. Physical Properties8.1 Slag cement shall conform to the physical requirements of Table 1.9. Sampling9.1 The following sampling and testing procedures shall be used by the purchaser to verify compliance with this specification.NOTE 3Sulfur in granulated blast-furnace slag is
23、 present predominantly as sulfide sulfur. In most cases, instrumental analyses, such as x-rayfluorescence, cannot differentiate sulfide sulfur from sulfate. Determine and report the sulfide sulfur content separately, and do not include it in theSO3calculations.9.2 Take random grab samples either fro
