| Use advice for data set | When using this data set for Life Cycle Assessment (LCA), consider that the scope of evaluation includes raw meal preparation, clinker calcination, and cement preparation, but does not account for the environmental load caused by the consumption of clay resources nor the impact of iron powder as an iron correction material. Furthermore, when modeling the use phase behavior or interpreting the results, it is important to note that only nitrogen oxides, sulfur dioxide, carbon dioxide, and dust emissions are considered. Ensure that LCA studies incorporating this data are restricted to the use of portland cement in contexts with comparable technological applicability and industrial operating parameters. |
| Technical purpose of product or process | This data set describes the production process of portland cement with a 28-day compressive strength of 42.5 MPa, utilizing alternative rotary kiln technologies. The described portland cement is suitable for construction applications where high strength cement is required, such as the construction of infrastructure, buildings, and bridges. It is specifically applicable to the cement industry within Heilongjiang Province, involving the stages from raw meal preparation to cement preparation. |

| Model description | The functional unit is the performance of 1kg cement with a 28-day compressive strength of 42.5MPa, that is, 1Fu=42.5kgMPa. The scope of evaluation is raw meal preparation, clinker calcination and cement preparation. The environmental load caused by the consumption of clay resources is not considered for the time being. Iron powder is an iron correction material, and its environmental impact will not be considered. The wastes considered to be emitted at the output end of the product system mainly include nitrogen oxides, sulfur dioxide, carbon dioxide and dust. |
