16、ic System3. 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 ce-ment consisting of portland cement with either a slag cement ora pozzolan.3.1.2 ternary blended cement, na bl

17、ended hydraulic ce-ment consisting of portland cement with either a combinationof two different pozzolans, or slag cement and a pozzolan.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 ce

18、ments for general concrete con-struction.4.1.1.1 Type ISPortland blast-furnace slag cement.4.1.1.2 Type IPPortland-pozzolan cement.4.1.1.3 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.

19、1, where (X) equals the targeted percentage of slag orpozzolan in the product expressed as a whole number by massof the final blended product, within the allowable variation asstated in 14.3.4.2.2 The naming practice for ternary blended cements shallbe made by adding the suffixes (AX) and (BY) to th

20、e Type ITdesignation under 4.1.1, where:A is either “S” for slag cement, or “P” for pozzolan,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, or “P” for pozzolan, andY is the targeted percentage by mass of co

21、nstituent 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 thepozzolan content first.NOTE 2Examples of the naming practice per 4.2.1 and 4.3 are shownbelow (all percentages by mas

22、s):Binary blended cement with 80 % portland cement and 20 % slagcement = IS(20).Binary blended cement with 85 % portland cement and 15 % pozzolan= IP(15).Ternary blended cement with 70 % portland cement, 20 % slag cementand 10 % pozzolan = IT(S20)(P10).Ternary blended cement with 65 % portland cemen

23、t, 25 % of onepozzolan and 10 % of another pozzolan = IT(P25)(P10).Ternary blended cement with 60 % portland cement and 20 % ofslag cement and 20 % pozzolan = Type IT(P20)(S20).4.2.3 A simplified naming practice is used in this standardfor practicality and clarity when referring to specific require-

24、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 3)NOTE 3Examples of the simplified naming practices per 4.2.3 areshown below:1) An exam

25、ple 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 cement contents 70 %, indicated asIS(70); ternary blended cements with a pozzolan content less than theslag cement content and the slag

26、cement content is less than 70 %,indicated as IT(PS70).2) An example when requirements are applicable to only one constitu-ent within a specific range (%) of that constituent can be found in 8.2,where testing is required only when the slag cement content is 25 %.Because the requirement is based on t

27、he slag cement content only with norelation to the pozzolan content, a simplified naming practice is employedand the range of ternary blended cements are indicated 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 suffi

28、x (A) to any of the abovetypes. The air-entraining option is specified in combinationwith any of the other special properties where required.NOTE 4A given mass of blended cement has a larger absolute volumethan the same mass of portland cement. This should be taken intoconsideration in purchasing ce

29、ments and in proportioning concrete mix-tures.4.3.2 Moderate sulfate resistance or moderate heat of hy-dration, or both, when desired by the purchaser, shall bespecified by adding the suffix (MS) or (MH), respectively, tothe type designation under 4.1.1.4.3.3 High sulfate resistance, when desired by

30、 the pur-chaser, shall be specified by adding the suffix (HS) to the typedesignation under 4.1.1.NOTE 5Special characteristics attributable to slag or pozzolan willvary based on quantities contained within the blended cements.4.3.4 Low heat of hydration, when desired by the purchaser,shall be specif

31、ied by adding the suffix (LH) to the typedesignation under 4.1.1.TABLE 1 Chemical RequirementsCement TypeAApplicableTestMethodIS( 70),IT(PS70)IS($ 70),IT(S$70)IP,IT(P$S)Magnesium oxide (MgO), max, % C114 . . 6.0Sulfate reported as SO3, max, %BC114 3.0 4.0 4.0Sulfide reported as S2-, max, % C114 2.0
