Scope

This Standard specifies the method of determination for cement fineness with
Blaine air permeability apparatus.
This Standard is applicable to the determination of specific surface area of
cements and other powdery materials that this Standard applies whose
specific surface is 2000 cm2/g~ 6000 cm2/g, and it is not applicable to the
determination for cellular or micro-powdery material.
