Article Preview

The synthesis conditions and mechanical performance of alite-rich cement clinker were investigated by the orthogonal test method. Sintering temperature, sintering time and contents of strontium oxide or strontium sulfate were taken as the influencing factors for the orthogonal test. The experimental results show that the optimal sintering temperature and sintering time are 1450 °C and 60 min, and the best strontium oxide or strontium sulfate content in the clinker is 1.5% and 0.5%, respectively. The doping of strontium oxide or strontium sulfate can promote the formation of alite mineral. That is beneficial to the increase of cement strength. The early strength of cement can be improved by addition of strontium oxide, and the long strength of cement can be increased through adding a little of strontium sulfate.
