3、e1.1 This specification 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

4、some performance requirements 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 state

5、d ineach system may 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

6、by appropriate conversion, 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 footnotes,which provide e

Terminology3.1 DefinitionsThe terms used in this specification aredefined in Terminology C219, except for the following terms:3.1.1 binary blended cement, na blended hydraulic c

19、e-ment consisting of portland cement with either a slag, apozzolan, or a limestone.3.1.2 slag, nthe term slag is used within this standard todenote either slag cement or granulated blast-furnace slag.3.1.3 ternary blended cement, na blended hydraulic ce-ment consisting of portland cement with either

20、 a combinationof two different pozzolans, slag and a pozzolan, a pozzolan anda limestone, or a slag and a limestone.NOTE 2Relevant terms in Terminology C219 applicable to thisstandard include portland cement, portland-cement clinker, hydrauliccement, slag cement, granulated blast-furnace slag, pozzo

21、lan, and calciumsulfate. Limestone is defined in Terminology C51.4. Classification4.1 This specification applies to the following types ofblended cement that generally are intended for use as indicated.4.1.1 Blended hydraulic cements for general concrete con-struction.4.1.1.1 Type ISPortland blast-f

22、urnace 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 bemade by adding the suffix (X) to the type designation under4.1.1, where (X) equals the targete

23、d 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 15.3.4.2.2 The naming practice for ternary blended cements shallbe made by adding the suffixes (AX) and (BY) to the Type ITdesignatio

24、n 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 is the targeted percentage by mass of

25、 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 15.3. If X and Y are the same, list the twoconstituents in alphabetical order by constituent type(limestone, pozzolan, or slag).NOTE 3Examples of the nam

26、ing practice in accordance with 4.2.1 and4.2.2 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 cement with 90 % portland cement and 10 %

27、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).Ternary blended cement with 60 % portland cement and 20 % ofs

28、lag 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).4.2.3 A simplified naming practice is used in this standar

29、dfor practicality and clarity when referring to specific require-ments for binary and ternary blended cements that are appli-cable to a range of products or in ternary blended cementswhen requirements are applicable to only one constituentwithin a specific range (%). (See Note 4.)NOTE 4Examples of t

30、he simplified naming practices in accordancewith 4.2.3 are shown below:1)An example when requirements are applicable to a range of productscan be found in Table 1, where the maximum SO3content of 3 % appliesto: binary blended cements with slag contents 70 %, indicated asIS(70); and ternary blended c

31、ements with a pozzolan content less thanthe slag content and the slag content is less than 70 %, indicated asIT(PS70).2) An example when requirements are applicable to only one constitu-ent within a specific range (%) of that constituent can be found in 9.2,where testing is required only when the sl

32、ag content is 25 %. Because therequirement is based on the slag content only with no relation to thepozzolan or limestone content, a simplified naming practice is employedand the range of ternary blended cements is indicated as Type IT(S25).4.3 Special Properties:4.3.1 Air-entraining cement, when de

33、sired by the purchaser,shall be specified by adding the suffix (A) to the typedesignation under 4.1.1.NOTE 5Agiven mass of blended cement has a larger absolute volumethan the same mass of portland cement. This should be taken intoconsideration in purchasing cements and in proportioning concrete mix-

34、tures.4.3.2 Moderate heat of hydration, when desired by thepurchaser, shall be specified by adding the suffix (MH) to thetype designation under 4.1.1.4.3.3 Moderate sulfate resistance, when desired by thepurchaser, shall be specified by adding the suffix (MS) to thetype designation under 4.1.1.4.3.4

35、 High sulfate resistance, when desired by thepurchaser, shall be specified by adding the suffix (HS) to thetype designation under 4.1.1.C595/C595M 15124.3.5 Low heat of hydration, when desired by the purchaser,shall be specified by adding the suffix (LH) to the typedesignation under 4.1.1.4.3.6 Resi

36、stance to alkali-silica reactive aggregateexpansion, when desired by the purchaser, shall be specified byadding the suffix (R) to the type designation under 4.1.1.NOTE 6Special characteristics attributable to slag, pozzolan or lime-stone will vary based on quantities contained within the blended cem

37、ents.Type IT cements with greater than 5 % limestone and Type ILcements arenot permitted as moderate (MS) or high (HS) sulfate resistance cements,pending results of further research.5.
