Use advice for data set
| Users of this dataset should specifically model the 'two grinding and one burning' process typical of cement clinker production operations and incorporate direct CO2 emissions from the consumption of various fuels, predominantly coal, used in the manufacturing process. Additionally, users must account for indirect CO2 emissions resulting from electricity consumption during production. It is advisable to use the data carefully, specifically for the carbon footprint of cement clinker production, and apply suitable scaling for different functional units referencing the estimated value of 1t of clinker when full life cycle data is not available. |

Technical purpose of product or process
| The sulpho-aluminate cement clinker described in this dataset is intended for use as a critical component in the construction industry. It is used for the production of sulpho-aluminate cement, which is noted for its rapid hardening properties, low-temperature calcination, and potential environmental benefits given its capacity to incorporate industrial wastes such as calcium carbide slag. |

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. .
