Variation in cement
Cement has several varying properties. These are for example:
0. Composition of clinker minerals
0. Microstructure of clinker minerals
0. Amount and form of calcium sulphate
0. Amount and form of alkalies
0. Material temperature
0. Particle size gradation (fineness)
0. Particle shape
Until now, the most observed single property of cement has been the fineness that is expressed in
specific surface according to the Blaine method. Several tests and long time monitoring, however,
have shown that Blaine fineness is not a sufficient parameter for explaining the variations in the
properties of fresh concrete mix or early age properties of hardened concrete. This seems to be the
