Use advice for data set | When utilizing this LCA data set, users should be aware that it specifically targets the general cement variety produced with a new dry process technology in China and represents industry practices as of 2011 with an upward trend. The functional unit is 1kg of general cement with a clinker content of 70%. The data is focused on inventory indicators relevant to the ECER (Energy Conservation and Emission Reduction) policy objectives and may be incomplete. Methodological considerations such as system boundaries, assumptions, and data quality should be carefully examined before applying this data in an LCA. The data should ideally be updated to reflect any significant technological or policy changes that have occurred since 2011. |
Technical purpose of product or process | The data represents the typical applications of common portland cement produced using the new dry process technology in China, which by 2011 accounted for 89.0% of the national production and was still increasing. This common portland cement is primarily used in construction applications, including the creation of concrete structures, buildings, roads, and other infrastructure projects. It is pertinent to a wide range of construction projects due to its general-purpose properties and strength. |
