In order to reflect the present environmental impact of China's cement industry, taking into account the adjustment of the industry structure and development status in recent years, and considering the differences in cement production technology and the size of different enterprises, China's cement industry is classified into four categories: large new dry process (>4000 tons of clinker per day), medium new dry process (2000~4000 tons of clinker per day), small new dry process (<2000 tons of clinker per day), and shaft kiln (<2001 tons of clinker per day).新型干法，市场份额占61.82%；2000~4000吨-熟料/日，规模份额占23.21%。为反应现阶段中国水泥工业的环境影响，结合近年来中国水泥工业结构调整和发展现状，考虑到水泥生产技术水平的高低以及不同规模水泥企业的差异，将中国水泥工业分为以下四类：大型新型干法（>4000吨-熟料/日）、中型新型干法（2000~4000吨-熟料/日）、小型新型干法（<2000吨-熟料/日）和立窑（<2000吨-熟料/日）。13The new dry method accounts for 61.82% of the market share; 2000~4000 tons-clinker/day, the scale share accounts for 23.21%. In order to reflect the environmental impact of China's cement industry at this stage, combined with the structural adjustment and development status of China's cement industry in recent years, and taking into account the level of cement production technology and the differences between cement companies of different sizes, this study divides China's cement industry into the following four categories : Large new dry process (>4000 tons-clinker/day), medium-sized new dry process (2000~4000 tons-clinker/day), small new dry process (<2000 tons-clinker/day) and vertical kiln ( <2000 tons-clinker/day).新型干法，市场份额占61.82%；2000～4000 吨-熟料/日，规模份额占23.21%。为反应现阶段中国水泥工业的环境影响，结合近年来中国水泥工业结构调整和发展现状，考虑到水泥生产技术水平的高低以及不同规模水泥企业的差异，本研究将中国水泥工业分为以下四类：大 型新型干法（>4000 吨-熟料/日）、中型新型干法 （2000~4000 吨-熟料/日）、小型新型干法（<2000 吨-熟料/日）和立窑（<2000 吨-熟料/日）。The medium new dry process used in this dataset refers to the production of common Portland cement with a daily clinker production rate of 2000 to 4000 tons. This cement is utilized broadly in the construction industry for creating concrete, precast structural elements, and other building materials. The production technique is significant as it represents a balance between output capacity and environmental considerations in China's cement industry, being applicable mainly to medium-scale cement plants.本数据集中的中型新型干法是指每日产生2000至4000吨熟料的通用硅酸盐水泥生产。这种水泥广泛用于建筑行业，用于制作混凝土、预制结构元素以及其他建筑材料。这种生产技术在中国水泥产业中占有重要地位，因为它在产量能力和环境考虑之间实现了平衡，主要适用于中等规模的水泥厂。KiHfb0JEvoB1HZxYLSecdaPbnBe.pngTake 1 ton of general cement produced in China with a clinker content of 70% as the functional unit.

Users should consider the typical market share and ensure the representative nature of the data when applying it to environmental impact studies. Variations in technology and scale between different companies in China's cement industry should influence the selection and application of this data.在将此数据集用于水泥产品的生命周期评估时，必须考虑特定的生产技术（中型新干法）和代表中型水泥厂的运营规模。用户应当考虑典型市场份额，并确保在应用于环境影响研究时数据的代表性。应考虑中国水泥产业不同公司在技术和规模上的差异，以影响此数据的选择和应用。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!, jingguo92@gmail.comjingguo92@gmail.comjingguo92@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:40:18.306195+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=3b6acaf6-17a8-4701-8082-5f6687effa1c&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 millInput930.0930.0Limestone石灰石clayInput130.0130.0Clay粘土gypsum stone (CaSO4-dihydrate)Input50.050.0Gypsum石膏hard coal; 26.3 MJ/kgInput119.17119.17Coal consumption during clinker burning.
