1、Designation: C595/C595M 121Standard Specification forBlended Hydraulic Cements1This standard is issued under the fixed designation C595/C595M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in p

2、arentheses 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.1NOTENote 2 was corrected editorially in July 2012.1. Scope*1.1 This specific

3、ation pertains to blended hydraulic cementsfor both general and special applications, using slag, pozzolan,limestone, or some combination of these, with portland cementor portland cement clinker or slag with lime.NOTE 1This specification prescribes ingredients and proportions,with some performance r

4、equirements whereas Performance SpecificationC1157 is a hydraulic cement specification in which performance criteriaalone govern the products and their acceptance.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system ma

5、y not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard. Values in SI units or inch-pound units shallbe obtained by measurement in SI units or inch-pound unitsor by appropriate con

6、version, using the Rules for Conversionand Rounding given in IEEE/ASTM SI 10, of measurementsmade in other units or SI units. Values are stated in only SIunits when inch-pound units are not used in practice.1.3 The text of this standard refers to notes and footnoteswhich provide explanatory material

22、percentage of slag,pozzolan or limestone, in the product expressed as a wholenumber by mass of the final blended product, within theallowable variation as stated in 14.3.4.2.2 The naming practice for ternary blended cements shallbe made by adding the suffixes (AX) and (BY) to the Type ITdesignation

23、under 4.1.1, where:A is either “S” for slag cement, “P” for pozzolan, or“L” for limestone,whichever is present in larger amount by mass, andX is the targeted percentage by mass of constituent A, andB is either “S” for slag cement, “P” for pozzolan, or“L” for limestone, andY is the targeted percentag

24、e by mass of constituent B.Both X and Y values are expressed as a whole number bymass of the final blended product, within the allowablevariation as stated in 14.3. If X and Y are the same, list the twoconstituents in alphabetical order by constituent type (lime-stone, pozzolan, or slag).NOTE 2Examp

25、les of the naming practice per 4.2.1 and 4.2.2 areshown below (all percentages by mass):Binary blended cement with 80 % portland cement and 20 % slagcement = Type IS(20).Binary blended cement with 85 % portland cement and 15 % pozzolan= Type IP(15).Binary blended cement with 90 % portland cement and

26、 10 % limestone= Type IL(10).Ternary blended cement with 70 % portland cement, 20 % slag cementand 10 % pozzolan = Type IT(S20)(P10).Ternary blended cement with 65 % portland cement, 25 % of onepozzolan and 10 % of another pozzolan = Type IT(P25)(P10).Ternary blended cement with 60 % portland cement

27、 and 20 % ofslag cement and 20 % pozzolan = Type IT(P20)(S20).Ternary blended cement with 80 % portland cement, 10 % pozzolanand 10 % limestone = Type IT(L10)(P10).Ternary blended cement with 75 % portland cement, 15 % slag cementand 10 % limestone = Type IT(S15)(L10).4.2.3 A simplified naming pract
