The air permeability specific surface of a powder material is a singleparameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder. The SI units are m 2 ·kg −1 ("mass specific surface") or m 2 ·m −3 ("volume specific surface").
Different brand of cement should possess standard fineness. Therefore it is neccessary to determine the fineness of cement. Apparatus: 90m sieve, Blaine''s air permeability apparatus, Nonreacting liquid Dibutyl thalate,Mercury, China dish, Weight box, Balance. Procedure: 1. Blaine''s air .
