Blaine Fineness ASTM C 204
American Association State
Highway and Transportation Officials Standard
AASHTO No.: T 153
Designation: C 204 – 07
Standard Test Methods for
Fineness of Hydraulic Cement by Air-Permeability
Apparatus1
This standard is issued under the fixed designation C 204; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
2.2 Other Document:
No. 114 National Institute of Standards and Technology
Standard Reference Material3
BS 4359: 1971 British Standard Method for the Determination of Specific Surface of Powders: Part 2: Air Permeability Methods4
1. 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.
1.2 The values stated in SI units are to be regarded as the standard. 1.3 This standard does not
