Users should note that the average data reflects the weighted consumption of raw materials across various production scales and technologies, including large, medium, and small new dry process facilities, as well as shaft kilns. The methodological consideration must be the use of this data in the context of cement with a 70% clinker content. The data assumes China-specific technology mix and should only be used as such without extrapolation to other regions without appropriate adjustments. Furthermore, users looking to study specific types or qualities of cement production should acquire more detailed data rather than relying on this average.本生命周期评价（LCA）数据集基于不同水泥生产技术及其运营规模的市场份额。用户应注意，平均数据反映了横跨不同生产规模和技术的原材料加权消耗，包括大型、中型、小型新型干法装置以及立窑。方法论上的考虑必须是将这些数据用于含有70%熟料的水泥的背景下。数据假定了中国特定的技术组合，只应当作为此类使用，未经适当调整不宜外推至其他地区。此外，希望研究特定类型或质量的水泥生产的用户应该获取更详细的数据，而不是依赖这个平均值。Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044.清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。Tiangong LCI Data Working Group天工LCI数据工作小组#REF!, ysqsophia@gmail.comysqsophia@gmail.comysqsophia@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:42:24.237157+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=1129701c-e75d-4573-9d2b-c2016d9a1b05&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and useslimestone, crushed, for millInput920.0920.0Limestone石灰石clayInput130.0130.0Clay粘土gypsum stone (CaSO4-dihydrate)Input50.050.0Gypsum石膏hard coal; 26.3 MJ/kgInput126.49126.49Coal consumption during clinker burning.
