Investigating multicomponent breakage in cement grinding ...

2015-06-01  During the blended cement production the components are ground within the same mill and as a result of different grindabilities, relatively harder components accumulate in coarser fractions while the softer ones accumulate in finer fractions (Schiller, 1992, Tsivilis et al., 1999). Hence, the control of the fineness of the components independently is impossible and this leads to overgrinding ...

Cement hydration - Understanding Cement

As the dormant period progresses, the paste becomes too stiff to be workable. At the end of the dormant period, the alite and belite in the cement start to react, with the formation of calcium silicate hydrate and calcium hydroxide. This corresponds to the main period of hydration (Stage III), during which time concrete strengths increase.
