This product is the result of heating limestone, gypsum, and clay, and is then ground together with other materials to produce different types of cement. It is a critical component used in the construction industry for buildings, bridges, roads, and other infrastructures.普通硅酸盐水泥熟料是水泥制造中的主要产品，用作各类水泥中的粘合剂。该产品是将石灰石、石膏和粘土加热后的结果，并与其他材料一起磨细以生产不同类型的水泥。它是建筑行业中用于建筑物、桥梁、道路和其他基础设施的关键组成部分。The functional unit is unknown, but it is estimated to be 1t of clinker based on literature data. The entire life cycle of cement production includes the mining of raw materials and the entire process of producing raw materials into cement. In the process of cement production, we mainly consider the "two grinding and one burning" of the cement production process and the direct output of carbon dioxide to the environment from the consumption of various fuels (mainly coal), as well as the indirect output of carbon dioxide to the environment from the electricity consumed in cement production. .功能单元未知，根据文献数据推测为1t熟料。水泥生产的全生命周期包括原料的开采以及将原料生产成水泥的全过程。在水泥生产的过程中主要考虑水泥生产工艺的“两磨一烧”和各种燃料的消耗量（主要是煤炭）对环境直接输出的二氧化碳，以及水泥生产所消耗的电量对环境间接输出的二氧化碳。LCI resultNone无None无None无None无Carbon emission value: CO2 mass, unit process carbon footprint data accumulation.碳排放值：CO2质量，单元过程碳足迹数据累加。None无光文涛, 隋晓萌, 王鹏刚, 田砾, & 赵明海.

(2022). 采用固废制备的高贝利特硫铝酸盐水泥碳足迹核算与分析. 青岛理工大学学报, 43(4), 34–40.For Life Cycle Assessment purposes, it is essential to accurately account for the direct and indirect carbon emissions during the 'two grinding and one burning' stages of the cement clinker production process. The direct emissions are mainly due to the fuels consumed, primarily coal, where as indirect emissions are related to the electricity used. Estimations should be based on a functional unit of 1 ton of clinker, as derived from literature data. Users should only account for the carbon footprint directly associated with the production of cement clinker, excluding the impacts of raw material extraction and other upstream or downstream processes. When utilizing this data set, integration with broader construction material databases is advised to assess total environmental impact in a construction project context.在进行生命周期评估时，准确计算水泥熟料生产过程中“两磨一烧”阶段的直接和间接碳排放至关重要。直接排放主要由消耗的燃料（主要是煤炭）产生，而间接排放与所使用的电量有关。估算应基于1吨熟料的功能单元，该单元来自文献数据。用户只应计算与水泥熟料生产直接相关的碳足迹，排除原材料开采和其他上游或下游过程的影响。使用这个数据集时，建议与更广泛的建筑材料数据库整合，以在建筑项目背景下评估总体环境影响。Only focus on the carbon footprint of cement clinker production.只关注水泥熟料生产的碳足迹。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.comysqsophia@gmail.comysqsophia@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:40:48.722304+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=6887fd3f-6ea0-45d0-a631-84033295c783&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 carbonateInput1300.01300.0Limestone石灰石gypsumInput50.050.0Gupsum石膏Clay, bentonite, in groundInput300.0300.0Clay黏土hard coalInput125.0125.0Coal consumption煤耗ElectricityInput385.2385.2Power consumption电耗carbon dioxide (fossil)Output1028.651028.65Carbon emissions.
