2、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 NOTENote 2 was corrected editorially in July 2012.1. Scope*1.1
3、 This specification pertains to blended hydraulic cements for both general and special applications, using slag, pozzolan,limestone, or some combination of these, with portland cement or portland cement clinker or slag with lime.NOTE 1This specification prescribes ingredients and proportions, with s
4、ome performance requirements whereas Performance Specification C1157 isa hydraulic cement specification in which performance criteria alone govern the products and their acceptance.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stat
5、ed in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard. Values in SI units or inch-pound units shall be obtained bymeasurement in SI units or inch-pound units
6、 or by appropriate conversion, using the Rules for Conversion and Rounding givenin IEEE/ASTM SI 10, of measurements made in other units or SI units. Values are stated in only SI units when inch-pound unitsare not used in practice.1.3 The text of this standard refers to notes and footnotes which prov

24、 the type designation under 4.1.1, where(X) equals the targeted percentage of slag, pozzolan or limestone, in the product expressed as a whole number by mass of the finalblended product, within the allowable variation as stated in 14.3.4.2.2 The naming practice for ternary blended cements shall be m

26、” for pozzolan, or“L” for limestone, andY is the targeted percentage by mass of constituent B.Both X and Y values are expressed as a whole number by mass of the final blended product, within the allowable variation asstated in 14.3. If X and Y are the same, list the two constituents in alphabetical
