4、57 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 stated ineach system may not be exact equivalents; therefore, eachsyste

21、ssification4.1 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-furnace slag cement.4.1.1.2 Type IPPortland-pozzolan cement.4.1.1.3 Type
22、 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 targeted percentage of slag,pozzolan or limestone, in the product expressed as
23、 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 ITdesignation under 4.1.1, where:A is either “S” for slag, “P” for pozzolan, or“L”
24、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 constituent B.Both X and Y values are expressed as a whole number byma
25、ss 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 naming practice per 4.2.1 and 4.2.2 areshown below (all percentages by mas
26、s):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 % limestone= Type IL(10).Ternary blended cement with 70 % portland cement, 20 % slagand
27、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 % ofslag and 20 % pozzolan = Type IT(P20)(S20).Ternary blended cement with 80 % portland ce
28、ment, 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 standardfor practicality and clarity when referring to specific require-ments for binary and
29、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 (%).

When the manufacture
32、r supplies cement under this provision, supporting data shall be supplied to the purchaser.See Note 9.CInsoluble residue maximum limit does not apply to ternary blended cements.DFor ternary blended cements with limestone, loss on ignition is a maximum of 10.0 % by mass.C595/C595M 142NOTE 4Examples o
33、f the simplified naming 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 contents 70 %, indicated asIS(70); and ternary blended cements with
34、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 slag content i
35、s 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 desired by the
36、 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-tures.4.3.2
37、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 High sulfat
38、e resistance, when desired by thepurchaser, shall be specified by adding the suffix (HS) to thetype designation under 4.1.1.4.3.5 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 Resistance to alkali-silica rea
39、ctive 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 cements.Type IT cements with g
40、reater than 5 % limestone and Type ILcements arenot permitted as moderate (MS) or high (HS) sulfate resistance cements,pending results of further research.5.
