The Effect of Dolomite Additive on Cement Hydration

2017-1-23  The studies of hydration process in the mixtures of cement with limestone powder, dolomite powder and limestone – dolomite additive were reported by Nocuń-Wczelik et al. [6]. In the pastes hydrating with fine grained dolomite powder the crystallization of products is accelerated and as a consequence the strength development is improved.

Study of using light-burned dolomite ores as raw

2018-10-17  According to Figure 5, the hydration process of MOS cement produced by dolomite is similar to MOS cement with light-burned magnesite (LBM) as raw material based on the report by Wu et al. (2017). In contrast, the hydration-heat release rate of MOS cement produced by light-burned dolomite ores was roughly three times lower than the MOS cement ...

Magnesium oxysulphate cement (MOC, Magnesia / Sorel’s Cement), discovered by Sorel S.T. in 1867 and has versatile cementing characteristics. It is prepared by the reaction of magnesium sulphate with magnesia in aqueous solution. Dolomite is used as inert filler to absorb the heat evolved during the exothermic formations of oxysulphate cement.
