The Application of Manganese Slag in the Prodution of Early-Strength Sulphoaluminate Cement

In this paper,the mineralogical constituents,the alkaline coefficients and the alumina-sulphur ratios of the sulphoaluminate cement clinker are designed in term of the chemical compositions of slag and the properties of the minerals in the clinker.Some practical mixtures in this system are prepared with the addition of other materials.The calcine temperature of the prepared mixtures is determined in terms of the X-ray analysis data of clinkers at different sintering temperatures and the data from pertinent literatures.The prepared cement is tested and its physical properties me- asured.The results obtained show that the prepared cement with the features of early-strength and favourable stability of strength comes up to the Standards for 425~# early-strength sulphoaluminate cement in all performances.This indicates that the manganese slag may be favourably used to produce early-strength sulphoalminate cement.
