Use advice for data set
| For Life Cycle Assessment purposes, it is essential to accurately account for the direct and indirect carbon emissions during the 'two grinding and one burning' stages of the cement clinker production process. The direct emissions are mainly due to the fuels consumed, primarily coal, where as indirect emissions are related to the electricity used. Estimations should be based on a functional unit of 1 ton of clinker, as derived from literature data. Users should only account for the carbon footprint directly associated with the production of cement clinker, excluding the impacts of raw material extraction and other upstream or downstream processes. When utilizing this data set, integration with broader construction material databases is advised to assess total environmental impact in a construction project context. |

Technical purpose of product or process
| Ordinary Portland Cement Clinker, a primary product in cement manufacturing, serves as the binder in various types of cement. This product is the result of heating limestone, gypsum, and clay, and is then ground together with other materials to produce different types of cement. It is a critical component used in the construction industry for buildings, bridges, roads, and other infrastructures. |

Model description
|
The functional unit is unknown, but it is estimated to be 1t of clinker based on literature data. The entire life cycle of cement production includes the mining of raw materials and the entire process of producing raw materials into cement. In the process of cement production, we mainly consider the "two grinding and one burning" of the cement production process and the direct output of carbon dioxide to the environment from the consumption of various fuels (mainly coal), as well as the indirect output of carbon dioxide to the environment from the electricity consumed in cement production. .
