General Information
SIGNIFICANCE AND USE
5.1 This method is intended to help manufacturers determine the relative pack-set tendency of their cement(s). The test establishes a pack-set index which, when properly correlated with field performance, is useful in predicting or preventing field unloading difficulties.
5.2 The test is an aid to routine control during cement production and is not suitable for specification purposes.
5.3 In general, field performance of cement flowability is satisfactory when the pack-set index as determined on freshly ground cement averages 0 to 15 and is unsatisfactory when the index exceeds 25. Any prediction of field performance of cement flowability measuring 16 to 25 is tenable. These are general ranges and the field performance of individual cements may not necessarily fall within these ranges. Additional conditions, after the cement has left the control of the manufacturing facility, can affect the apparent pack set index as well.
5.4 Any attempt to apply the critical range of pack-set index numbers based on freshly ground cement to job cement without special treatment of the sample would be problematic. The test is a “GO-NO-GO” type of test and should not be used for specification purposes.
5.5 The pack-set index of field cement can be evaluated in terms of the pack-set index ranges of that cement as determined when freshly-ground. This comparison can aid the manufacturer in producing cement that offers the best field performance for pack-set properties.
5.6 Silo storage of cement may result in a greater amount of consolidation than this method is designed to induce, and the resulting forces required to overcome that consolidation are not measured by this test method.
5.7 Pack set is not to be confused with “warehouse set” which results from surface hydration of the cement from adsorbed moisture.
SCOPE
1.1 This test method covers the determination of the pack-set index, which provides an indication of the mechanical force needed to overcome the consolidation of portland and blended hydraulic cements.
1.2 The pack-set index number provides a numerical value useful for manufacturers who desire to measure and control the effect that vibration-induced consolidation has upon the manufactured cement.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. Values stated in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the rules of Conversion and rounding given in Standard IEEE/ASTM SI 10, of measurements made in other units.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (WARNING—Fresh hydraulic-cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.2)
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ABSTRACT
This specification covers the criteria and tests to be used for determining whether a processing addition meets the requirement. When proposed addition is accepted for general use in Portland cement, tests shall be made on cements prepared from at least five different clinkers. These clinkers shall represent two Type I cements, one Type II cement, and two Type III cements. Processing additions shall be evaluated by comparing cements containing the addition to otherwise identical cements from the same source without the addition, or containing a processing addition. The compressive strength and flexural strength of the concrete made with cement containing the addition shall be compared with strengths obtained with the control cement at similar ages. The properties of the materials shall be determined through the following tests in accordance with the following standard: chemical analysis of the cement, compound composition, fineness of cement, normal consistency, time of setting, autoclave expansion, air content of mortar, compressive strength of mortar, and drying shrinkage of mortar.
SCOPE
1.1 This specification pertains to the criteria and tests to be used for determining whether a(n) organic or inorganic processing addition, when used in the recommended amount at the option of the cement producer in the manufacture of hydraulic cements, meets the requirements as prescribed by definition in Specifications C150/C150M, C1157/C1157M, C845/C845M, and C595/C595M. The materials listed in the following former ASTM Specifications shall be considered as meeting the organic processing additions requirements of this specification:
C150/C150M – 62, for Portland Cement
C205 – 58 T, for Portland Blast-Furnace Slag Cement
C340 – 58 T, for Portland Pozzolan Cement
C358 – 58, for Slag Cement
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The following safety hazards caveat pertains only to the test methods described in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ABSTRACT
This specification covers methods to investigate the effectiveness of a material to beneficially change the properties of hydraulic cements when the material is interground with the clinker during manufacture of the cement. Cement, mortar, and concrete shall be tested and the individual grades shall conform to specified values of autoclave expansion, drying shrinkage, normal consistency, standard consistency, setting time, compressive strength, false set, water content, flexural strength, bond to steel, volume change, resistance to freezing and thawing, and bleeding. Accelerating addition, retarding addition, set-control addition, water-reducing addition, water-reducing and accelerating addition are detailed.
SCOPE
1.1 This specification covers methods to investigate the effectiveness of a material to beneficially change the properties of hydraulic cements when the material is incorporated during manufacture of the cement.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The effect of additions in cement may markedly change properties other than those they are intended to modify. This specification is designed to test for such changes. Table 1 sets forth values for those properties of cement pastes and mortars that would permit a judgment of the changes effected by an addition. Likewise, Table 2 sets forth similar criteria for concrete. Certain additions may be found effective for more than one purpose as indicated in 3.1.4 and 3.1.5.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
This method is intended to help manufacturers determine the relative pack-set tendency of their cement(s). The test establishes a pack-set index which, when properly correlated with field performance, is useful in predicting or preventing field unloading difficulties.
The test is an aid to routine control during cement production and is not suitable for specification purposes.
In general, field performance of cement flowability is satisfactory when the pack-set index as determined on freshly ground cement averages 0 to 15 and is unsatisfactory when the index exceeds 25. Any prediction of field performance of cement flowability measuring 16 to 25 is tenable. These are general ranges and the field performance of individual cements may not necessarily fall within these ranges. Additional conditions, after the cement has left the control of the manufacturing facility, can affect the apparent pack set index as well.
Any attempt to apply the critical range of pack-set index numbers based on freshly ground cement to job cement without special treatment of the sample would be problematic. The test is a “GO-NO GO” type of test and should not be used for specification purposes.
The pack-set index of field cement can be evaluated in terms of the pack-set index ranges of that cement as determined when freshly-ground. This comparison can aid the manufacturer in producing cement that offers the best field performance for pack-set properties.
Silo storage of cement may result in a greater amount of consolidation than this method is designed to induce, and the resulting forces required to overcome that consolidation are not measured by this test method.
Pack set is not to be confused with “warehouse set” which results from surface hydration of the cement from adsorbed moisture.
SCOPE
1.1 This test method covers the determination of the pack-set index, which provides an indication of the mechanical force needed to overcome the consolidation of portland cement.
1.2 The pack-set index number provides a numerical value useful for manufacturers who desire to measure and control the effect that vibration-induced consolidation has upon the manufactured cement.
1.3 The values stated in SI units are to be regarded as the standard. Values stated in Inch-Pound units are for informational purposes only and are enclosed in parentheses. Values stated in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the rules of Conversion and rounding given in Standard IEEE/ASTM SI 10, of measurements made in other units.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (WARNING—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and ittuse upon prolonged exposure).
