The dataset's functional unit is based on the production of 1 ton of cement. LCA practitioners should take into account the production line's operating days per year and the integration of mixed solid waste materials in the cement composition. Special attention must be given to the emission data during the clinker calcination stage, which includes CO2, SO2, and NOx. Due to regional variances in raw material composition and energy consumption patterns, the geographical and technological applicability should be considered when applying this data to cement manufacturing elsewhere. 当使用这个数据集进行水泥产品的生命周期评价（LCA）时，请确保您的LCA范围涵盖了原料采集、煤粉制备、熟料煅烧和水泥粉磨阶段。数据集的功能单位基于生产1吨水泥。LCA实践者应当考虑到生产线每年的运行天数和混合固体废料在水泥成分中的结合。在熟料煅烧阶段的排放数据，包括CO2、SO2和NOx，必须给予特别关注。由于原材料组成和能源消费模式的地区差异，在将这些数据应用到其他地区的水泥制造时，应当考虑地理和技术的适用性。 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 2024-03-19T21:18:09+08:00 2024-04-20T14:40:52.414691+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=c82888ce-bf99-4fc8-af3f-75f13b545492&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 841.4 841.4 Limestone 石灰石 shale Input 54.0 54.0 Shale 页岩 sandstone Input 27.66 27.66 Sandstone 砂岩 iron, powder Input 16.95 16.95 Iron powder 铁粉 gypsum stone (CaSO4-dihydrate) Input 51.5 51.5 Gupsum 石膏 ash Input 154.3 154.3 Fly ash 粉煤灰 blast furnace slag Input 257.0 257.0 Blast furnace slag 矿渣 hard coal;  26.3 MJ/kg Input 92.0 92.0 Coal 煤炭 Electricity Input 318.06 318.06 Electricity.
