Effect of MgO on the composition and properties of alite-sulphoaluminate cement
The effect of MgO on the composition and properties of alite- sulphoaluminate cement clinker with commercial-grade raw materials such as limestone, clay, gypsum and fly ash as starting materials has been investigated in order to confirm results previously obtained with pure raw materials. The experiment results confirm that the addition of MgO at about 2-5% can improve the burnability of raw meal, promote the absorption of free lime and the formation of C3 S and C4A3S over bar. In addition, it is shown that this can also increase the strength development of the cement and shorten the setting time. When the content of MgO reaches about 8%, the strength of the cement decreases slightly and the setting time is extended.
