| Use advice for data set | When using this dataset for life cycle assessment of Portland-composite cement, consider the following: 1) If incorporating recycling in your model, ensure that only the transportation and preparation process impacts of industrial wastes and auxiliary materials like slag and fly ash are accounted for, excluding their production processes. 2) The dataset reflects pollutant emissions from the production of electricity from the national average grid, raw material extraction, and average transportation distances of 100km for inputs. 3) The life cycle functional unit is based on 1 tonne of cement, and the system boundary encompasses cement production, raw material production and transportation, as well as electricity production, excluding the use and processing of cement. |
| Technical purpose of product or process | The Portland-composite cement produced by the new dry process precalciner kiln is intended for a variety of construction applications requiring high strength and durability. It is specifically designed for large-scale production, ensuring compatibility with more environmentally friendly manufacturing methods and compliance with advancing productivity needs within China’s cement industry. This cement is typically used in construction projects such as buildings, bridges, and roads. |

| Technology description including background system | This article selects a pre-decomposition kiln-drying cement production model. The new dry pre-decomposition cement production technology is based on suspension preheating and pre-decomposition technology. It is a production technology that is more in line with environmental protection requirements and meets high productivity requirements, and has become the future development trend of China's cement industry. Therefore, the selection of new dry pre-decomposition cement production technology as cement model production technology has advanced and environmentally friendly requirements. |

| Model description | The life cycle functional unit is selected as 1t of cement to construct the life cycle model.The cement industry system boundary includes the production of cement, the production and transportation of raw materials, and the production of electricity, but does not include the use and processing of cement.For auxiliary materials such as slag and fly ash, only the transportation and preparation process will be considered, and the production process will not be considered. |
