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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

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 manometer shall be filled to the midpoint line with a nonvolatile, nonhygroscopic liquid of low viscosity and density. Link to Active This link will always route to the current Active version of the standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

The calibration of the air permeability apparatus shall be made using the standard reference material. The timer shall have a positive starting and stopping mechanism. 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.

However, the user should exercise judgement in determining its suitability with regard asstm fineness measurements of cements with densities, or porosities that differ from those assigned to Standard Reference Material No. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials.

Caution should be taken when handling mercury and mercury containing products. Active view current version of standard. 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 axtm this test method demonstrated acceptable astk.

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.

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.

Two test methods are given: 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 disk shall be constructed of noncorroding metal, and shall fit the inside of the cell snugly. 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 permeability cell shall consist of a rigid cylinder, constructed of austenitic stainless steel. 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 given: When standardization is required in order to achieve agreement between test method A and test method B, the apparatus shall be standardized according satm the requirements prescribed.
