The fineness of cement is a property that 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.

This method has been adopted in Europe as the definitive means of determining the fineness of cement and other powder materials.

The system is supplied complete with stainless steel cell, perforated disc and plunger, manometer U-tube, aspirator, bottle of manometer liquid and a box of filter papers.This method has been adopted in Europe as the definitive means of determining the fineness of cement and other powder materials.

It is necessary to know the specific gravity of cement for various reasons related to its quality and use. In particular it will be necessary to determine the specific gravity as part of the determination of the specific surface of a cement. The ELE Le Chatelier Flask is a high specification unit that is individually calibrated and supplied with calibration certificate.
