3、c 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 some performance requirements, whereas Performanc

4、e Specification C1157is a 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 stated in eachsystem may not be exact equivalents;

5、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 or by appropriate conversion, using the Rules

6、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 provide explanatory material. These notes and foot

7、notes(excluding those in tables and figures) are not requirements of the standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standards, Guides

Terminology3.1 DefinitionsThe terms used in this specification are defined in Terminology C219, except for the following terms

20、:3.1.1 binary blended cement, na blended hydraulic cement consisting of portland cement with either a slag, a pozzolan, ora limestone.3.1.2 slag, nthe term slag is used within this standard to denote either slag cement or granulated blast-furnace slag.3.1.3 ternary blended cement, na blended hydraul

21、ic cement consisting of portland cement with either a combination of twodifferent pozzolans, slag and a pozzolan, a pozzolan and a limestone, or a slag and a limestone.NOTE 2Relevant terms in Terminology C219 applicable to this standard include portland cement, portland-cement clinker, hydraulic cem

22、ent, slagcement, granulated blast-furnace slag, pozzolan, and calcium sulfate. Limestone is defined in Terminology C51.4. Classification4.1 This specification applies to the following types of blended cement that generally are intended for use as indicated.4.1.1 Blended hydraulic cements for general

23、 concrete construction.4.1.1.1 Type ISPortland blast-furnace slag cement.4.1.1.2 Type IPPortland-pozzolan cement.4.1.1.3 Type ILPortland-limestone cement.4.1.1.4 Type ITTernary blended cement.4.2 Reporting:4.2.1 The naming practice for blended cements shall be made by adding the suffix (X) to the ty

24、pe 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 15.3.4.2.2 The naming practice for ternary blended cements shall be made by

25、adding the suffixes (AX) and (BY) to the Type ITdesignation under 4.1.1, where:A is either “S” for slag, “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, “P” for pozzolan, or“L”

26、 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 15.3. If X and Y are the same, list the two constituents in alphabetical order by constituent

27、type (limestone, pozzolan,or slag).NOTE 3Examples of the naming practice in accordance with 4.2.1 and 4.2.2 are shown below (all percentages by mass):Binary blended cement with 80 % portland cement and 20 % slag= Type IS(20).Binary blended cement with 85 % portland cement and 15 % pozzolan= Type IP(

28、15).Binary blended cement with 90 % portland cement and 10 % limestone= Type IL(10).Ternary blended cement with 70 % portland cement, 20 % slagand 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).

29、Ternary blended cement with 60 % portland cement and 20 % ofslag and 20 % pozzolan = Type IT(P20)(S20).Ternary blended cement with 80 % portland cement, 10 % limestoneand 10 % pozzolan = Type IT(L10)(P10).C595/C595M 182Ternary blended cement with 75 % portland cement, 15 % slagand 10 % limestone = T

30、ype IT(S15)(L10).4.2.3 A simplified naming practice is used in this standard for practicality and clarity when referring to specific requirementsfor binary and ternary blended cements that are applicable to a range of products or in ternary blended cements when requirementsare applicable to only one

31、 constituent within a specific range (%). (See Note 4.)NOTE 4Examples of the simplified naming practices in accordance with 4.2.3 are shown below:1) An example when requirements are applicable to a range of products can be found in Table 1, where the maximum SO3 content of 3 % applies to:binary blen

32、ded cements with slag contents 70 %, indicated as IS(70); and ternary blended cements with a pozzolan content less than the slag contentand the slag content is less than 70 %, indicated as IT(PS70).2) An example when requirements are applicable to only one constituent within a specific range (%) of

33、that constituent can be found in 9.2, wheretesting is required only when the slag content is 25 %. Because the requirement is based on the slag content only with no relation to the pozzolan orlimestone content, a simplified naming practice is employed and the range of ternary blended cements is indi

34、cated as Type IT(S25).4.3 Special Properties:4.3.1 Air-entraining cement, when desired by the purchaser, shall be specified by adding the suffix (A) to the type designationunder 4.1.1.NOTE 5Agiven mass of blended cement has a larger absolute volume than the same mass of portland cement. This should

35、be taken into considerationin purchasing cements and in proportioning concrete mixtures.4.3.2 Moderate heat of hydration, when desired by the purchaser, shall be specified by adding the suffix (MH) to the typedesignation under 4.1.1.4.3.3 Moderate sulfate resistance, when desired by the purchaser, s

36、hall be specified by adding the suffix (MS) to the typedesignation under 4.1.1.4.3.4 High sulfate resistance, when desired by the purchaser, shall be specified by adding the suffix (HS) to the type designationunder 4.1.1.4.3.5 Low heat of hydration, when desired by the purchaser, shall be specified

37、by adding the suffix (LH) to the type designationunder 4.1.1.NOTE 6Special characteristicsproperties attributable to slag, pozzolan or limestone will vary based on quantities contained within the blendedcements.NOTE 7Guide C1778 provides guidance on use of blended hydraulic cements in concrete mixtu
