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.

ASTM C Standard

The Blaine air-permeability apparatus consists essentially of a means of drawing a definite quantity of air through a prepared bed of asgm of definite porosity. Historical Version s – ashm previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The disk shall be constructed of noncorroding metal, and shall fit the inside of the cell snugly.

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. The plunger shall be constructed of austenitic stainless steel and shall fit into the cell.

Historical Version s – view previous versions of standard. The manometer shall be filled to the midpoint line with a nonvolatile, nonhygroscopic liquid of low viscosity and density. 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 astn centimetres per gram, or square metres 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 aastm than absolute fineness values are obtained. When standardization is required x204 order to achieve agreement between test method Sstm and test method B, the apparatus shall be standardized according to the requirements prescribed.

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.

The filter paper disks shall be circular, with smooth edges, and shall have the same diameter as the inside of the cell. Two test methods are ashm Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials.

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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The automated test method shall employ apparatus designed either on the principles of the Blaine air-permeability method or apparatus asstm on the air-permeability principles of the Lea and Nurse method.

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. The timer shall have a positive starting and stopping mechanism. The U-tube manometer shall be constructed according asstm the design indicated.

Work Item s – proposed revisions of this standard.

The calibration of the air permeability apparatus shall be made using the standard reference material. This abstract is a brief summary of the c2044 standard.
