The resource-based industry in Ordos City, Inner Mongolia is mainly composed of five parts. They are coal-electricity industry chain, coal-to-oil industry chain, coal-to-gas industry chain, coal chemical industry chain and coal-electricity-aluminum industry chain. In the development of the above industries, a large amounts of solid wastes such as coal gangue, carbide slag and desulfurized gypsum will be discharged. It can be seen from the previous laboratory research that coal gangue, carbide slag and desulfurized gypsum can replace bauxite, limestone and gypsum respectively to produce all-solid waste low-carbon cementitious materials. However, at present, the products produced by cement plants in Ordos area are still mainly ordinary Portland cement. An all-solid waste low-carbon cementitious material production line with coal gangue, carbide slag and desulfurization gypsum as raw materials has not yet been built. Therefore, it is necessary to evaluate the environmental impact of each production link before the construction or upgrading of the production line.
