The invention discloses belite-sulphoaluminate-ferrous aluminate cement which comprises the following components by mass percent: 38-70% of beta-C2S, 27-37% of C4A3S-(refer to the description) and 3-25% of C4AF. The invention further discloses a preparation method of the belite-sulphoaluminate-ferrous aluminate cement. The preparation method comprises the following steps: with industrial waste residue and industrial gypsum as the raw materials, mixing the raw materials with aluminous corrective addition namely bauxite or tailing bauxite, forming, performing hydrothermal reaction, crushing, calcining and grinding to obtain the belite-sulphoaluminate-ferrous aluminate cement. According to the invention, the low-carbon belite-sulphoaluminate-ferrous aluminate cement is prepared at low temperature; in addition, limestone is not used, so that no carbon dioxide is generated to increase the environmental pressure; moreover, the calcining temperature is low, so that the energy consumption is low, and the preparation method is a low-carbon and environment friendly preparation method.
