Sulphoaluminate cement clinker using sulfur tailings as raw materials and preparation method thereof

The invention provides a sulphoaluminate cement clinker using sulfur tailings as raw materials and a preparation method thereof. Through being metered in parts by weight, the sulphoaluminate cement clinker is prepared from the following components: 5 to 20 parts of sulfur tailings, 20 to 40 parts of aluminum ash, 40 to 50 parts of carbide slag and 5 to 20 parts of titanium gypsum. The sulfur tailings are used for completely replacing sulfurated and ferriferous raw materials for production of conventional sulphoaluminate cement clinker; calciferous, aluminiferous and silicic raw materials are partially replaced; after the powder is ground to a certain fineness degree, the ore formation in the cement clinker is controlled through alkalinity coefficient Cm and sulfur-aluminum ratio P; the sulfur tailings and components such as the aluminum ash, the carbide slag and the titanium gypsum are used for preparing the sulphoaluminate cement clinker. According to the prepared sulphoaluminate cement clinker, the sulfur t
