| 数据集使用建议 | 使用此数据时需考虑其系统边界为“摇篮到大门”的部分闭合。它包括从原材料提取到运输的生命周期阶段，而不考虑水泥的使用和处置。为了进行准确的生命周期评估(LCA)建模，请确保系统边界与您研究的范围相匹配。如果将研究范围扩展到“摇篮到大门”之外，额外阶段必须单独考虑。回收和废物处理阶段仅包括到大门；随后的影响应根据具体项目需求进行建模。重要的是要认识到，废物输入被视为生命周期影响数据集相关原材料基础的一部分。 |
| 产品或过程的技术目的 | 此数据集涉及硅酸盐水泥（波特兰水泥）的生产，其中混合了废水泥和水泥加固剂作为部分原材料基础。生产的水泥适用于各种建筑应用，包括但不限于混凝土结构、建筑物和基础设施项目的创建。特别设计以支持高强度要求和通过利用回收废料的可持续性措施。 |

| 建模说明 | 使用一吨水泥和固体废弃水泥作为功能单元。将系统边界定义为“摇篮到大门”，部分闭合。考虑了材料开采、原材料制备、熟料煅烧、磨碎和运输的过程，不包括水泥使用和废弃阶段。固体废弃物的生命周期始于废弃阶段。 |
