Market shares of cement production process technologies and sizes: large new dry process (>4000 t-clinker/day), 29.32%; medium new dry process (2000-4000 t-clinker/day), 23.21%; small new dry process (<2000 t-clinker/day), 9.29%; shaft kiln (<2000 t-clinker/day), 38.18%.中国的平均数据是基于各水泥生产工艺技术和规模的市场份额以及各自的原材料消耗计算获得。水泥生产工艺技术和规模的市场份额：大型新型干法（>4000吨-熟料/日），29.32%；中型新型干法（2000~4000吨-熟料/日），23.21%；小型新型干法（<2000吨-熟料/日），9.29%；立窑（<2000吨-熟料/日），38.18%。18Market share of cement production process technology and scale: large-scale new dry process (>4000 tons-clinker/day), 29.32%; medium-sized new dry process (2000~4000 tons-clinker/day), 23.21%; small-scale new dry process Method (<2000 tons-clinker/day), 9.29%; vertical kiln (<2000 tons-clinker/day), 38.18%.水泥生产工艺技术和规模的市场份额：大型新型干法（>4000 吨-熟料/日），29.32%；中型新型干法 （2000~4000 吨-熟料/日），23.21%；小型新型干法（<2000 吨-熟料/日），9.29%；立窑（<2000 吨-熟料/日，38.18%。The common portland cement described in this dataset is used in a variety of construction applications, ranging from infrastructure to residential buildings. It represents a general-purpose construction material typical for large-scale projects including bridges, highways, and skyscrapers within China.该数据集描述的通用硅酸盐水泥在各种建筑应用中使用，范围从基础设施到住宅建筑。它代表了中国大型项目典型的通用建筑材料，包括桥梁、高速公路和摩天大楼。MJgTbpr3Co08jMxaA1vcMqb1nrf.pngTake 1 ton of general cement produced in China with a clinker content of 70% as the functional unit. The scope of the system boundary is defined as: the mining and processing of raw materials, the production of energy, the manufacturing and sales of cement, and the transportation processes involved in the middle.取中国生产1t熟料含量为70%的通用水泥作为功能单元。系统边界的范围界定为：原材料的开采和加工、能源的生产、水泥的制造和销售，以及中间涉及到的运输过程。LCI resultNone无None无None无The life cycle inventory of electricity production and coal mining comes from the early data collection of Sichuan University; the life cycle inventory of road transportation comes from Ma Liping's master's thesis. Considering the transportation of raw materials and final products in the cement production process, it is assumed that the transportation mileage is as follows: 3km of road transportation for raw materials such as limestone and clay; 50km for coal road transportation; 200km for cement products.电力生产和煤炭开采的生命周期清单来自于四川大学前期的数据收集；公路运输的生命周期清单来自于马丽萍的硕士论文；考虑到水泥生产过程原材料和最终产品的运输，假设运输里程如下：石灰石、粘土等原材料公路运输3km；煤炭公路运输50km；水泥产品公路运输200km。None无None无姜睿 & 王洪涛.

The data should be adapted for use in LCA models that account for similar technology and scale distributions. The system boundary includes mining and processing of raw materials, energy production, and transportation. Caution should be taken when extrapolating this data to other regions or conditions not represented by the dataset. The LCI data is based on allocations for transportation distances specific to this dataset, which may require adjustment if applying to different transportation scenarios.使用此数据集时，用户应将地理范围和不同生产技术和规模的平均市场份额作为背景信息考虑。数据应适应于考虑类似技术和规模分布的LCA模型中使用。系统边界包括原材料的开采和加工、能源生产和运输。在将此数据外推到数据集未表示的其他地区或条件时应谨慎。LCI数据基于特定于此数据集的运输距离分配，如果应用于不同的运输场景可能需要调整。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.com2024-04-19T19:02:06+08:002024-04-20T14:40:21.787876+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=819dca5d-3347-461b-acae-77b5b4dd39f4&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 usescalcium carbonateInput1600.01600.0Limestone石灰岩clayInput130.0130.0Clay粘土sandstoneInput0.3390.339Sandstone砂岩gypsumInput50.550.5Gypsum石膏freshwaterInput369.0369.0Freshwater新鲜水hard coal; 26.3 MJ/kgInput192.0192.0Coal.
