C01.25 - Fineness

ABSTRACT
This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: test method A is the reference test method using the manually operated standard Blaine apparatus, while test method B permits the use of automated apparatus that has in accordance with the qualification requirements of this test method demonstrated acceptable performance. The Blaine air-permeability apparatus consists essentially of a means of drawing a definite quantity of air through a prepared bed of cement of definite porosity. The permeability cell shall consist of a rigid cylinder, constructed of austenitic stainless steel. The disk shall be constructed of noncorroding metal, and shall fit the inside of the cell snugly. The plunger shall be constructed of austenitic stainless steel and shall fit into the cell. The filter paper disks shall be circular, with smooth edges, and shall have the same diameter as the inside of the cell. The U-tube manometer shall be constructed according to the design indicated. The manometer shall be filled to the midpoint line with a nonvolatile, nonhygroscopic liquid of low viscosity and density. The timer shall have a positive starting and stopping mechanism. The calibration of the air permeability apparatus shall be made using the standard reference material. The automated test method shall employ apparatus designed either on the principles of the Blaine air-permeability method or apparatus based on the air-permeability principles of the Lea and Nurse method. When the specific surface values determined by an automated apparatus are to be used for acceptance or rejection of cement, the method used shall comply with the qualification requirements. When standardization is required in order to achieve agreement between test method A and test method B, the apparatus shall be standardized according to the requirements prescribed.
SCOPE
1.1 This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: Test Method A is the Reference Test Method using the manually operated standard Blaine apparatus, while Test Method B permits the use of automated apparatus that has in accordance with the qualification requirements of this test method demonstrated acceptable performance. Although the test method may be, and has been, used for the determination of the measures of fineness of various other materials, it should be understood that, in general, relative rather than absolute fineness values are obtained.  
1.1.1 This test method is known to work well for portland cements. However, the user should exercise judgement in determining its suitability with regard to fineness measurements of cements with densities, or porosities that differ from those assigned to Standard Reference Material No. 114 or No. 46h.  
1.2 The values stated in SI units are to be regarded as the standard.

ABSTRACT
This test method covers the determination of the density of hydraulic cement. Its particular usefulness is in connection with the design and control of concrete mixtures. The density of hydraulic cement is defined as the mass of a unit volume of the solids. The apparatus to be used is a Le Chatelier flask which is circular in cross-section. This flask shall be thoroughly annealed before being graduated. They shall be of sufficient thickness to ensure reasonable resistance to breakage. Each flask shall bear a permanent identification number and the stopper, if not interchangeably ground, shall bear the same number. Interchangeable ground-glass parts shall be marked on both members with the standard-taper symbol, followed by the size designation. The standard temperature shall be indicated, and the unit of capacity shall be shown by the letters “mL” placed above the highest graduation mark. Kerosene, free of water, or naphtha shall be used in the density determination. The flask shall be filled with either of the liquids mentioned to a point on the stem between the 0 and the 1-mL mark. The inside of the flask shall be dried above the level of the liquid, if necessary, after pouring. The first reading shall be recorded after the flask has been immersed in the water bath. A quantity of cement shall be introduced in small increments at the same temperature as the liquid. A vibrating apparatus may be used to accelerate the introduction of the cement into the flask and to prevent the cement from sticking to the neck. After all the cement has been introduced, the stopper shall be placed in the flask and the flask shall be rolled in an inclined position, or gently whirl it in a horizontal circle, so as to free the cement from air until no further air bubbles rise to the surface of the liquid. If a proper amount of cement has been added, the level of the liquid will be in its final position at some point of the upper series of graduations. The final reading shall be recorded after the flask has been immersed in the water bath. The difference between the first and the final readings represents the volume of liquid displaced by the mass of cement used in the test. The cement density can now be determined.

ABSTRACT
This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the No. 50, No. 100, and No. 200 sieves. The following apparatus shall be utilized: wet test sieves; spray nozzle; pressure gage; balance; weights; brush; dry test sieves; and NBS SRM No. 1004 (glass bead standard). Dry sieve standardization shall be performed by determining the correction factors and by preparing the standard samples. Wet sieve calibration shall follow and shall utilize the sieve correction factor. The procedure for wet sieving shall include the following: weighing of the sample; recording the weight and transferring the sample quantitatively to a clean dry sieve; wetting the sample thoroughly with a gentle stream of water; removing the sieve from under the nozzle and adjusting the pressure of the spray nozzle; returning the sieve to its position under the nozzle and washing it; moving the sieve in the spray with a circular motion; rinsing the sieve with distilled or deionized water immediately after removing it from the spray; blotting the lower surface of the screen cloth with a damp, clean cloth; drying the sieve and residue in an oven or over a hot plate; cooling the sieve; brushing the residue from the sieve; and weighing the sieve on a balance.
SCOPE
1.1 This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the 300-μm (No. 50), the 150-μm (No. 100), and the 75-μm (No. 200) sieves.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

ABSTRACT
This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: test method A is the reference test method using the manually operated standard Blaine apparatus, while test method B permits the use of automated apparatus that has in accordance with the qualification requirements of this test method demonstrated acceptable performance. The Blaine air-permeability apparatus consists essentially of a means of drawing a definite quantity of air through a prepared bed of cement of definite porosity. The permeability cell shall consist of a rigid cylinder, constructed of austenitic stainless steel. The disk shall be constructed of noncorroding metal, and shall fit the inside of the cell snugly. The plunger shall be constructed of austenitic stainless steel and shall fit into the cell. The filter paper disks shall be circular, with smooth edges, and shall have the same diameter as the inside of the cell. The U-tube manometer shall be constructed according to the design indicated. The manometer shall be filled to the midpoint line with a nonvolatile, nonhygroscopic liquid of low viscosity and density. The timer shall have a positive starting and stopping mechanism. The calibration of the air permeability apparatus shall be made using the standard reference material. The automated test method shall employ apparatus designed either on the principles of the Blaine air-permeability method or apparatus based on the air-permeability principles of the Lea and Nurse method. When the specific surface values determined by an automated apparatus are to be used for acceptance or rejection of cement, the method used shall comply with the qualification requirements. When standardization is required in order to achieve agreement between test method A and test method B, the apparatus shall be standardized according to the requirements prescribed.

ABSTRACT
This test method covers the determination of the density of hydraulic cement. Its particular usefulness is in connection with the design and control of concrete mixtures. The density of hydraulic cement is defined as the mass of a unit volume of the solids. The apparatus to be used is a Le Chatelier flask which is circular in cross-section. This flask shall be thoroughly annealed before being graduated. They shall be of sufficient thickness to ensure reasonable resistance to breakage. Each flask shall bear a permanent identification number and the stopper, if not interchangeably ground, shall bear the same number. Interchangeable ground-glass parts shall be marked on both members with the standard-taper symbol, followed by the size designation. The standard temperature shall be indicated, and the unit of capacity shall be shown by the letters “mL” placed above the highest graduation mark. Kerosene, free of water, or naphtha shall be used in the density determination. The flask shall be filled with either of the liquids mentioned to a point on the stem between the 0 and the 1-mL mark. The inside of the flask shall be dried above the level of the liquid, if necessary, after pouring. The first reading shall be recorded after the flask has been immersed in the water bath. A quantity of cement shall be introduced in small increments at the same temperature as the liquid. A vibrating apparatus may be used to accelerate the introduction of the cement into the flask and to prevent the cement from sticking to the neck. After all the cement has been introduced, the stopper shall be placed in the flask and the flask shall be rolled in an inclined position, or gently whirl it in a horizontal circle, so as to free the cement from air until no further air bubbles rise to the surface of the liquid. If a proper amount of cement has been added, the level of the liquid will be in its final position at some point of the upper series of graduations. The final reading shall be recorded after the flask has been immersed in the water bath. The difference between the first and the final readings represents the volume of liquid displaced by the mass of cement used in the test. The cement density can now be determined.

ABSTRACT
This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the No. 50, No. 100, and No. 200 sieves. The following apparatus shall be utilized: wet test sieves; spray nozzle; pressure gage; balance; weights; brush; dry test sieves; and NBS SRM No. 1004 (glass bead standard). Dry sieve standardization shall be performed by determining the correction factors and by preparing the standard samples. Wet sieve calibration shall follow and shall utilize the sieve correction factor. The procedure for wet sieving shall include the following: weighing of the sample; recording the weight and transferring the sample quantitatively to a clean dry sieve; wetting the sample thoroughly with a gentle stream of water; removing the sieve from under the nozzle and adjusting the pressure of the spray nozzle; returning the sieve to its position under the nozzle and washing it; moving the sieve in the spray with a circular motion; rinsing the sieve with distilled or deionized water immediately after removing it from the spray; blotting the lower surface of the screen cloth with a damp, clean cloth; drying the sieve and residue in an oven or over a hot plate; cooling the sieve; brushing the residue from the sieve; and weighing the sieve on a balance.
SCOPE
1.1 This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the 300-μm (No. 50), the 150-μm (No. 100), and the 75-μm (No. 200) sieves.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in  of measurements made in other units. Values are stated in SI units when inch-pound units are not used in practice.
1.3 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.

SIGNIFICANCE AND USE
The purpose of this test method is to determine whether or not the hydraulic cement under test meets the Wagner turbidimetric fineness requirements of the applicable hydraulic cement specification for which the test is being made. Fineness of the cement component is only one of the many characteristics that influence the strength capabilities of concrete.
SCOPE
1.1 This test method covers determination of the fineness of portland cement as represented by a calculated measure of specific surface, expressed as square centimetres of total surface area per gram, or square metres of total surface area per kilogram, of cement, using the Wagner turbidimeter.

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.

SCOPE
1.1 This test method covers determination of the fineness of hydraulic cement, using the Blaine air permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square meters per kilogram, of cement. Although the test method may be, and has been, used for the determination of the measures of fineness of various other materials, it should be understood that, in general, relative rather than absolute fineness values are obtained.
1.1.1 This test method is known to work well for portland cements. However, the user should exercise judgment in determining its suitability with regard to fineness measurements of cements with densities, or porosities that differ from those assigned to Standard Reference Material No. 114.  
1.2 The values stated in SI units are to be regarded as the standard.  
1.3  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.

SCOPE
1.1 This test method covers the determination of the fineness of hydraulic cement by means of the 45-[mu]m (No. 325) sieve.  
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound equivalents of SI units may be approximate.  
1.3 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.

SCOPE
1.1 This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the 300-[mu]m (No. 50), the 150-[mu]m (No. 100), and the 75-[mu]m (No. 200) sieves.  
1.2 The values stated in SI units are to be regarded as the standard.  
1.3 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.

SCOPE
1.1 This test method covers determination of the density of hydraulic cement. Its particular usefulness is in connection with the design and control of concrete mixtures.  
1.2 The density of hydraulic cement is defined as the mass of a unit volume of the solids.  
1.3 The values stated in SI units are to be regarded as the standard.  
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.

SCOPE
1.1 This test method covers determination of the fineness of portland cement as represented by a calculated measure of specific surface, expressed as square centimetres of total surface area per gram, or square meters of total surface area per kilogram, of cement, using the Wagner turbidimeter.  
1.2 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.  
1.3 The values stated in SI units are to regarded as the standard. The inch-pound equivalents may be approximate.

SIGNIFICANCE AND USE
3.1 The purpose of this test method is to determine whether or not the hydraulic cement under test meets the Wagner turbidimetric fineness requirements of the applicable hydraulic cement specification for which the test is being made. Fineness of the cement component is only one of the many characteristics that influence the strength capabilities of concrete.
SCOPE
1.1 This test method covers determination of the fineness of portland cement as represented by a calculated measure of specific surface, expressed as square centimetres of total surface area per gram, or square metres of total surface area per kilogram, of cement, using the Wagner turbidimeter.2  
1.2 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.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Values in SI units [or inch-pound units] shall be obtained by measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI 10 of measurements made in other units. Values are stated in SI units when inch-pound units are not used in practice.
WITHDRAWN RATIONALE
This test method covers determination of the fineness of portland cement as represented by a calculated measure of specific surface, expressed as square centimetres of total surface area per gram, or square metres of total surface area per kilogram, of cement, using the Wagner turbidimeter.
Formerly under the jurisdiction of Committee C01 on Cement, this test method was withdrawn in March 2018. This standard is being withdrawn without replacement due to its limited use by industry.1
