This production process uses mixed solid wastes, specifically slag and fly ash, as part of the raw materials. This type of cement is typically used in construction for a variety of structural applications where such strength classification is sufficient.该数据集描述了使用传统立窑方法在广州石井水泥厂生产32.5MPa抗压强度的普通硅酸盐水泥的过程。此生产过程中使用混合固废，具体为矿渣和粉煤灰，作为部分原材料。此类水泥通常用于建筑中的各种结构应用，其中该强度级别足够满足要求。1kg P·O 32.5 ordinary Portland cement was used as the functional unit for evaluation.

Users of this data set should take note that the Life Cycle Assessment is based on the specific resource and energy consumption profiles associated with the shaft kiln production technique at Guangzhou Shijing Cement Plant, as calculated by Di Xianghua. The functional unit for assessment is 1kg of 32.5MPa ordinary Portland cement. The scope of the study includes the stages from cement raw material mining to storage, excluding the consideration of industrial solid waste (slag and fly ash) as resource consumption, therefore not accounting for any pollutant emissions from these materials. When applying this data to other scenarios, it is crucial to adjust for technological differences if the processes differ significantly from the Guanzhou Shijing method.使用此数据集的用户应注意，生命周期评价基于与广州石井水泥厂立窑生产技术相关的特定资源和能源消耗概况，该数据由狄向华计算得出。评估的功能单位为1kg 32.5MPa 普通硅酸盐水泥。研究范围包括从水泥原料开采到储存的各个阶段，不将工业固体废弃物（矿渣和粉煤灰）作为资源消耗考虑，因此不计算这些材料的任何污染物排放。在将此数据应用于其他场景时，如果过程与广州石井方法有显著差别，调整技术差异至关重要。Industrial waste residues, including slag and fly ash, are not considered as resource consumption for industrial solid waste, and thus no pollutant emissions are accounted for.工业废渣包括矿渣、粉煤灰，对工业固体废弃物不考虑作为资源消耗，故没有污染物排放。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+08:002024-04-20T14:41:06.983913+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=e519de74-5d39-4216-b7f5-cb2093bbc826&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 carbonateInput1190.01190.0Limestone.
