3、t 2015.1. Scope Scope*1.1 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 ingredient
4、s and proportions, with some performance requirements, whereas Performance 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
5、 standard. The values stated 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
6、 units or inch-pound units 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 note

Terminology3.1 DefinitionsThe terms used in this specification are defined in Terminology C219, except for the following terms:3.1.1 binary blende
21、d 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 hydraulic cement consisting
22、 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 cement, slagcement, gra
23、nulated 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 concrete constructi

25、 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 adding the suffixes
26、(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” for limestone, andY
27、 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 type (limestone, poz
28、zolan,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(15).Binary blended c
29、ement with 90 % portland cement and 10 % limestone= Type IL(10).Ternary blended cement with 70 % portland cement, 20 % slagC595/C595M 162and 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).Ternar
30、y 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).Ternary blended cement with 75 % portland cement, 15 % slagand 10 % limestone = Type IT(S15)(L10).4.2
31、.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 constituent within
32、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 blended cements with sla
33、g 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 that constituent can
34、 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 indicated as Type IT(S25
35、).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 be taken into consid

37、 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 by adding the suffix
38、 (LH) to the type designationunder 4.1.1.4.3.6 Resistance to alkali-silica reactive aggregate expansion, when desired by the purchaser, shall be specified by adding thesuffix (R) to the type designation under 4.1.1.NOTE 6Special characteristics attributable to slag, pozzolan or limestone will vary b
39、ased on quantities contained within the blended cements. TypeIT cements with greater than 5 % limestone and Type IL cements are not permitted as moderate (MS) or high (HS) sulfate resistance cements, pendingresults of further research.5.
