| Predmet normy: | This European Standard describes three methods of determining the fineness of cement. The sieving method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling the production process. The air-jet sieving method measures the retention on sieving and is suitable for particles which substantially pass a 2,0 mm test sieve. It may be used to determine the particle size distribution of agglomerates of very fine particles. This method may be used with test sieves in a range of aperture sizes, e.g. 63 µm and 90 µm. The air permeability method (Blaine) measures the specific surface area (mass related surface area) by comparison with a reference material sample. |
