A sulphate-aluminium-like cement produced by using electrolytic manganese slag and the preparation method of the cement relate to the production of the sulphate-aluminium-like by using industrial wastes and the preparation method of the cement. The raw materials of the cement clinker of the invention contain limestone, electrolytic manganese slag, kaolin and soft coal, and dihydrate gypsum is added to the fired cement clinker; the preparation method comprises the following steps: using the limestone, electrolytic Manganese slag, kaolin and soft coal as the raw materials of the clinker; first,levigating and homogenizing the raw materials, and calcining the raw materials into the clinker at a relatively low temperature; then adding the dihydrate gypsum to the clinker according to the requirement and then levigating the mixture to be the finished product. The cement is characterized in that the firing temperature ranges from 150 DEG C to 200 DEG C which is lower than that of the common Portland cement, and the energy-saving advantage is obvious; the mixture proportion range of the components is wide; the mixing amount of the manganese slag is great; and the fired cement has wide application, and so on. The preparation method can be widely used for producing the sulphate-aluminium-like cement by using electrolytic the manganese slag, and is in particular applicable to the production of early strength cement, rapid-hardening high-strength cement, expansive cement and low-alkali cement, and the like.
