16、 of Units (SI): the Modern Metric 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.

17、2 ternary blended cement, na blended 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 indic

18、ated.4.1.1 Blended hydraulic cements 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

19、 the type designation under4.1.1, 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 t

20、he suffixes (AX) and (BY) to the 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 ta

21、rgeted percentage 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 thepozzolan content first.NOTE 2Examples of the naming practice per 4.2.1 and 4.3 are sho

22、wnbelow (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).Ternary blended cement with 70 % portland cement, 20 % slag cementand 10 % pozzolan = Type IT(S20)(P10).T

23、ernary 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 % ofslag cement and 20 % pozzolan = Type IT(P20)(S20).4.2.3 A simplified naming practice is used in this standardfor practical

24、ity 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 3)NOTE 3Examples of the simplified n

25、aming practices per 4.2.3 areshown 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 cement contents 70 %, indicated asIS(70); ternary blended cements with a pozzolan con

26、tent less than theslag cement content and the slag 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 co

27、ntent is 25 %.Because the requirement is based on the 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 t

28、he purchaser,shall be specified by adding the suffix (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

29、 should be taken intoconsideration in purchasing cements 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

30、.1.1.4.3.3 High sulfate resistance, when desired by 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.NOTE 6There are cases w

31、here performance of a cement is improvedwith SO3in excess of the Table 1 limits in this specification. Test MethodC563 is one of several methods a manufacturer can use to evaluate theeffect of sulfate content on cement characteristics. Whenever SO3contentof a cement exceeds Table 1 limits, Test Meth
