Use a representative dry cement powder sample, weigh it, and compact it into the permeability cell so it forms a uniform porous bed with the porosity specified by your chosen method. For accurate Blaine testing, consistent powder handling and packing matter more than a loose fill or an unevenly packed bed.

The sample should be prepared the same way each time, then assembled with the cell caps and seals before measurement. That consistency is important because Blaine fineness is calculated from air flow through the packed bed, so the sample form, packing force, and porosity all influence repeatability.
