| Use advice for data set | When utilizing this data set for Life Cycle Assessment (LCA) or other environmental studies, please take into consideration that the LCA method was not used for modeling, indicating that the environmental impacts may not be comprehensive. It is advised to supplement this data with additional emission statistics and product-specific information when available. The data is based on the production technology of Dalian Cement Company as of the information cutoff date and does not consider future technological changes or improvements. Ensure to account for the technological applicability of the data to your specific context and update the data as required for accuracy. Recycling and end-of-life considerations are not included in this data set, so these should be accounted for separately if relevant to the intended use. |
| Technical purpose of product or process | This data set describes the Portland-composite cement (32.5RMPa) production process on a modern dry process production line with a rotary kiln capacity of 5000 tonnes per day. This cement is typically used in construction applications, where moderate strength development is adequate, such as in residential buildings, pavements, and where sulfate resistance is not a primary concern. The unique composition is suitable for general concrete construction, precast units, masonry units, and for specific works such as dam construction or oil well cementing, according to the different product types manufactured by the company. |
