When using this data set for Life Cycle Assessment (LCA) of construction projects involving 42.5 MPa OPC, it is critical to include both the coal used for clinker calcination and the supplementary coal for waste heat power generation. The user should apply the accumulated unit process data for energy consumption and air pollution as per the LCI results. Ensure that the methodological framework of the LCA considers the full scope of the production process, from raw material extraction to cement grinding. Comparisons with other cement production data sets should consider technological variability, geographic specificity, and temporal relevance to ensure accurate and context-appropriate LCA results. 在使用该数据集进行包含42.5 MPa OPC的建筑项目生命周期评价（LCA）时，至关重要的是要包括用于熟料煅烧的煤和用于余热发电的补充煤。用户应根据LCI结果应用累加的单元过程数据用于能耗和大气污染。确保LCA的方法论框架考虑了从原材料提取到水泥磨粉的完整生产过程。与其他水泥生产数据集的比较应考虑技术变量性、地理特异性和时间相关性，以确保准确和上下文适当的LCA结果。 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.com ysqsophia@gmail.com ysqsophia@gmail.com 2024-04-19T19:02:06+08:00 2024-04-20T14:40:21.797324+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=a20a9fb3-7d8e-4fbb-a47e-233b82f2aa39&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses calcium carbonate Input 1060.0 1060.0 Limestone 石灰石 sandstone Input 90.4 90.4 Sandstone 砂岩 iron Input 61.6 61.6 Iron 铁 bauxite Input 65.3 65.3 Bauxite 铝矾土 gypsum Input 76.1 76.1 Gupsum 石膏 hard coal;  26.3 MJ/kg Input 394.0 394.0 Coal consumption 煤耗 heavy fuel oil Input 7.15 7.15 The original literature is fuel oil consumption (i.e. heavy oil). 原文献为燃料油消耗（即重油）。 natural gas, high pressure Input 0.657 0.657 Natural gas 天然气 carbon dioxide (fossil) Output 846.0 846.0 CO2.
