| Use advice for data set | Users of this LCA dataset should note that the information is specific to the production of 1kg of Portland cement clinker with a strength level of 52.5MPa using the new dry process technology. The data can be considered representative of the national average for this process in China as of 2011. Use this dataset for life cycle assessments of construction materials where this specific type of clinker is used. Care should be taken to consider the transportation of raw materials in the lifecycle analysis and to recognize that the dataset does not cover complete lifecycle data but is focused on inventory indicators relevant to ECER policy objectives. Users should supplement this dataset with additional specific data related to other lifecycle stages as necessary for their particular assessments. |
| Technical purpose of product or process | This dataset represents the Portland cement clinker production using the new dry process technology. Portland cement clinker is the essential component used in the production of Portland cement, which then can be used in the construction industry. It is applicable specifically to clinker with a strength rating of 52.5MPa, which is indicative of high-grade cement typically used for projects requiring a high level of structural integrity. Given the dominance of this process in China, it can be assumed to be reflective of the national production standard for high strength cement applications. |

| Model description | The study only focuses on general cement, and selects the domestically produced 1kg cement clinker with a strength level of 52.5MPa using a new dry process (assuming the national average is 52.5MPa) as the functional unit. In addition, when establishing the life cycle model, the transportation process of raw materials is also considered. |
