Blaine Apparatus


Blaine – Surface area analysis – Fineness:


The fineness of cement is a property which must be carefully controlled during the manufacturing process. The total specific surface of the cement represents the surface area available for hydration. Various methods are in use to measure the specific surface of cements. For most purposes air permeability methods produce accurate, repeatable results.
