At present, the raw materials used for cement production in Chongqing are mainly limestone, natural gypsum, sandstone, and blended stone, accounting for about 90%, 5%, and 3%, respectively. 固废包括矿渣、粉煤灰、石膏粉、煤渣、混掺石子、锅炉渣。重庆市有水泥企业近170家，2014年全年水泥总产量近7000万ｔ。目前重庆水泥原料主要是石灰石、天然石膏和砂岩及掺混石子等，占比分别约90%，5%和3%。 14 A factory in Chongqing 重庆市内某工厂 Solid waste includes slag, fly ash, gypsum powder, cinder, mixed gravel, and boiler slag. 固废包括矿渣、粉煤灰、石膏粉、煤渣、混掺石子、锅炉渣。 The data set describes cement production incorporating 21-35% alternative constituents derived from mixed solid wastes, which include slag, fly ash, gypsum powder, coal ash, blended stones, and boiler slag. Suitable applications of this particular cement type might be in construction projects where such alternative compositions are permitted and may contribute to sustainable building practices due to the utilization of waste materials. 该数据集描述了含有 21-35% 代用成分的水泥生产过程，这些代用成分来自于混合固废，包括矿渣、粉煤灰、石膏粉、煤渣、混掺石子和锅炉渣。这种特定类型的水泥可能适用于允许使用此类替代成分的建筑项目，并且因为利用了废弃物料，可能有助于可持续的建筑实践。 BQY1bImdro6DTcx1edPcFQ2mn5d.png The carbon footprint of production in Chongqing cement plants mainly includes the carbon footprint of direct combustion of fuel, the carbon footprint of electricity consumption, the physical and chemical reactions of raw materials and clinker calcination, etc.The main sources of carbon emissions in cement production are: first, clinker calcination; second, carbon emissions from direct and indirect combustion of fuel. More than 99% of the greenhouse gases emitted are CO2, so the "cement carbon footprint" only involves the CO2 carbon footprint and does not include other greenhouse gases. 重庆水泥厂内生产碳足迹主要包括燃料直接燃烧的碳足迹，电能消耗碳足迹、原材料的物化反应及熟料煅烧等。水泥生产的主要碳排放源，一是熟料煅烧；二是燃料直接燃烧和间接燃烧碳排放。排放的温室气体中99%以上为CO2，所以“水泥碳足迹”只涉及CO2碳足迹，不包括其他温室气体。 Partly terminated system None 无 None 无 None 无 None 无 None 无 杨李宁 & 付祥钊.

Users of the data set should focus solely on the carbon footprint of cement production, specifically considering the emission factors corresponding to the CO2 emissions. It is important to note that the carbon footprint covered here does not include other greenhouse gases. Special attention must be paid to the factory's use of alternative constituents when calculating the carbon footprint because the emissions profile may differ from conventional cement production. Ensure consistent accounting for such emissions if comparing with other data sets or when integrating into larger life cycle assessments. 数据集用户应专注于水泥生产的碳足迹，特别是要考虑与CO2排放相对应的排放因子。请注意，此处涉及的碳足迹不包括其他温室气体。在计算碳足迹时必须特别注意工厂使用的替代成分，因为与传统水泥生产相比，排放特征可能有所不同。确保在与其他数据集比较或在较大生命周期评估中集成时，对此类排放进行一致的核算。 Only focus on the carbon footprint of cement production. 只关注水泥生产的碳足迹。 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 2024-04-20T14:41:31.021737+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=26fd39e3-d284-4d1b-b2fe-0cc30ca6379d&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 944.9039401 944.9039401 Limestone 石灰石 sandstone Input 125.0830348 125.0830348 Sandstone 砂岩 Acid slag Input 190.5457506 190.5457506 Acid residue 酸渣 hard coal Input 160.3607945 160.3607945 Bituminous coal 烟煤 blast furnace slag Input 102.8329534 102.8329534 Blast furnace slag 矿渣 ash Input 104.9338978 104.9338978 Fly ash 粉煤灰 gypsum stone (CaSO4-dihydrate) Input 60.74568544 60.74568544 Gypsum powder 石膏粉 coal, powder Input 66.08596548 66.08596548 Coal slag 煤渣 stone Input 35.51676978 35.51676978 Mixed stone 混掺石子 Boiler slag Input 30.577662 30.577662 Boiler slag 锅炉渣 Electricity Input 0.0377892 0.0377892 Fire power generation.
