Users of this dataset should note that the data reflects the specific technological approach and environmental performance tied to Huaxin Cement Yidu Co., Ltd's technical reform indicators. The high-volume fly ash content (over 50% industrial waste slag admixture, with at least 40% consisting of slag and fly ash) should be considered when evaluating the environmental impact and applying the data to similar industrial contexts. The functional unit here is defined as the service performance of 1 kilogram of cement with a 28-day compressive strength of 42.5 MPa, crucial for comparative LCA studies. The scope of the research includes all phases from raw material pretreatment to cement storage; thus, users should include all these stages when using the data for the life cycle assessment of cement-related products. 该数据集的用户需注意，数据反映了与华新水泥宜都有限公司技术改革指标相关的特定工艺途径和环境性能。当评估环境影响并将数据应用于相似的工业环境时，应考虑高掺量粉煤灰内容（超过50%的工业废渣混合掺入量，至少40%包含矿渣和粉煤灰）。此处定义的功能单元为1千克的水泥具有的28天抗压强度42.5MPa的使用性能，这对比较生命周期评估研究至关重要。研究范围包括从原料预处理到水泥存储的所有阶段；因此，用户在使用该数据进行水泥相关产品的生命周期评估时，应包括所有这些阶段。 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 2024-04-20T14:40:31.456102+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=56e003a4-b6f5-4814-9d59-e7f0e0583a20&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 limestone, crushed, for mill Input 786.4 786.4 Limestone 石灰石 gypsum stone (CaSO4-dihydrate) Input 45.1 45.1 Gupsum 石膏 ash Input 200.0 200.0 Fly ash 粉煤灰 blast furnace slag Input 200.0 200.0 The original document is labeled as "slag" (i.e. blast furnace slag). 原文献是矿渣（即高炉矿渣） hard coal Input 88.472 88.472 The original data is 0.0822kg standard coal, here converted to hard coal, the conversion formula is 1kg hard coal = 0.929kg standard coal. 原始数据为0.0822kg标准煤，这里换算为硬煤，换算公式为1kg硬煤=0.929kg标准煤。 Electricity Input 370.8 370.8 Electricity 电力 particles (> PM10) Output 0.15 0.15 Dust, with an unspecified particle size, is treated as PM > 10 micrometers in diameter. 粉尘，未标明粒径，按PM>10处理。 sulfur dioxide Output 0.000562 0.000562 Sulfur dioxide.
