The entire production process includes mixing (time of 2 min), pressing (pressure of 3 MPa; dimension of 240 × 115 × 53 mm), and maintenance steps 包括在 WDC 粉碎预处理后加入适量骨料（即人造砂），制备免烧砖。整个生产过程包括搅拌（时间为 2 分钟）、压制（压力为 3 兆帕；尺寸为 240 × 115 × 53 毫米）和维护步骤The non-sintered bricks produced in this industrial process are used in construction projects that require building materials with specific dimensions (240 × 115 × 53 mm) and properties. These bricks are suitable for applications where fired bricks are not necessary or desired, and can be utilized in various types of construction work, such as in the creation of walls, pavements, and other structural elements.该工业过程生产的非烧结砖用于需要特定尺寸（240 × 115 × 53 毫米）和性质的建筑项目中。这种砖头可用于不需要或不希望使用烧结砖的应用场合，并可用于各种类型的建筑工作，如构建墙体、铺设路面及其他结构构件。AOc0bKArSoVFegxBpMdcJma8ndh.pngUnit process, single operationNone无The eFootprint online analysis platform developed by IKE Environmental Technology Co. was used to perform quantitative analysis of the full life cycle process, as part of the LCA作为生命周期评估的一部分，亿科环境技术有限公司开发的 eFootprint 在线分析平台用于对整个生命周期过程进行定量分析。None无None无Information on the raw materials, energy inputs and pollutant emission data were obtained from Mianyang Building Materials Manufacturing Co., Ltd. 有关原材料、能源投入和污染物排放数据的信息来自绵阳建材制造有限公司。None无None无Liu, W. et al. Comparative life cycle assessment of cement, sintered bricks and non-sintered bricks manufacturing using water-based drilling cuttings from shale gas production in the Sichuan Basin, China. J.

Comparative life cycle assessment of cement, sintered bricks and non-sintered bricks manufacturing using water-based drilling cuttings from shale gas production in the Sichuan Basin, China. J. Environ. Manage. 314, 115135 (2022).Besides, 1t WDC were chosen as the functional unit and all the input parameters of raw materials, auxiliary materials, energy consumption, transportation, and direct emissions were calculated in accordance with the functional unit.此外，选择 1t WDC 作为功能单位，并按照功能单位计算所有原材料、辅助材料、能耗、运输和直接排放的输入参数。When using this LCA dataset, users should note that 1 ton of WDC (Waste Derived Cementitious material) is defined as the functional unit. The cut-off rule has been applied, allowing exclusion of low-value materials weighing less than 1% of the final product, such as fly ash, from the inventory list. This exclusion may affect the comprehensiveness of the results. Users should ensure that this approach aligns with their methodological requirements and that any significant environmental impacts are not overlooked. The data obtained from Mianyang Building Materials Manufacturing Co., Ltd. should be contextually adapted and may require updating if applied in a different geographical or technological setting.在使用这组生命周期评估（LCA）数据时，用户需注意WDC（废弃物衍生胶凝材料）1吨被定义为功能单位。采用了截断规则，可从清单中排除重量不足最终产品1%的低价值材料，例如粉煤灰。这种排除可能会影响结果的全面性。用户应确保这种方法与其方法论要求一致，并且不会忽视任何重大环境影响。从绵阳建材制造有限公司获得的数据应根据具体情况进行调整，并且如果在不同的地理或技术环境中应用可能需要更新。The cut-off rule was adopted, meaning that low-value materials from upstream processes weighing less than 1% of the final product (Zhao et al., 2020), such as fly ash, could be ignored in the inventory.采用了截断规则，这意味着在清单中可以忽略来自上游工序、重量不到最终产品 1%的低价值材料（Zhao 等人，2020 年），如粉煤灰。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Wang xiangjin, r99rt4@163.com王湘锦, r99rt4@163.comr99rt4@163.comr99rt4@163.com2024-04-13T15:24:33+08:002024-04-20T14:51:31.715442+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=ef5e4760-f007-4f32-95c6-9989bbc636ac&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 usessandInput2310.02310.0MeasuredFly ashInput12.012.0Measuredportland cementInput530.0530.0MeasuredclayInput1000.01000.0MeasuredfreshwaterInput300.0300.0MeasuredElectricityInput342.0342.0Measuredbrickbat aggregateOutput4152.04152.0MeasuredRaw materials for bricks砖块粗原料particles (> PM10)Output0.123570.12357Measured
