Its high strength makes it suitable for concrete components like beams, slabs, and columns that require significant load-bearing capacity. This dataset specifically accounts for environmental impact when incorporating waste incineration into the cement production process. 该数据集中描述的具有42.5MPa强度等级的普通硅酸盐水泥通常用于建筑应用，例如构建基础设施、住宅和商业结构。其高强度使其适用于需要显著承载能力的混凝土组件，如梁、板和柱。该数据集特别考虑了在水泥生产过程中纳入废物焚烧时的环境影响。 Functional unit definition: Take the performance of 1t 42.5 ordinary Portland cement as a functional unit.

Users of this dataset should note that the functional unit is defined as the use performance of 1 tonne of 42.5 ordinary Portland cement. The system boundary for this LCA data is confined to the direct production process within the cement plant, which includes raw material entry, pretreatment, grinding of raw meal, calcination of raw meal, clinker grinding, until cement homogenization and storage. It does not account for upstream processes like raw material extraction, processing, or transportation. The geographical scope of this study is limited to the Beijing area, and users should be cautious when extrapolating this data to other regions or different production settings. 使用此数据集的用户应注意，功能单位定义为1吨42.5普通硅酸盐水泥的使用性能。该LCA数据的系统边界仅限于水泥厂内的直接生产过程，包括原料进场、预处理、生料磨、生料煅烧、熟料磨、直至水泥均化和储存。它不包括原料开采、加工或运输等上游过程。本研究的地理范围限于北京地区，用户在将这些数据外推至其他地区或不同的生产环境时应谨慎。 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 2024-04-20T14:41:27.447438+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=e9f202a1-129b-441a-968d-e7d7b4ec4c9f&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 1318.5 1318.5 Limestone 石灰石 clay Input 94.5 94.5 Clay-based raw materials 黏士质原料 iron, powder Input 27.0 27.0 Iron correction raw material 铁质校正原料 gypsum stone (CaSO4-dihydrate) Input 60.0 60.0 The proportion of gypsum is 5.5% 石育5.5% mixed materials, mineral Input 200.0 200.0 Mixed material 混合材 industrial waste (unspecified) Input 12.5 12.5 10.0 15.0 uniform Industrial waste 工业废弃物 hard coal;  26.3 MJ/kg Input 120.0 120.0 Coal consumption kg 煤耗kg Electricity Input 363.6 363.6 Power consumption 电耗 Nitrogen oxides Output 1.43 1.43 NOx NOx sulfur dioxide Output 0.003 0.003 SO2 SO2 particles (> PM10) Output 9.8 9.8 Dust, with an unspecified particle size, is treated as PM > 10 micrometers in diameter. 粉尘，未标明粒径，按PM>10处理。 carbon dioxide (fossil) Output 772.0 772.0 CO2. Since the volume of CO2 is generally not detected, the emissions are calculated according to the following formulas. CO2 generates the combustion of fossil energy such as fuel, coal-fired and other fossils, as well as limestone decomposition in cement production raw materials. (1) CO2 emissions of fossil energy combustion are calculated as follows: e = 3.67fqka. E is the emissions of CO2, KG; F is the consumption of fuel, kg; Q is fuel thermal mass, mj/kg; K is the carbon emissions coefficient of fuel; A is the carbon oxidation rate of fuel. (2) During the production of cement, the chemical reactions of raw materials limestone generate a large number of CO2 chemical reactions: CACO3 → Cao+CO2 ↑. The percentage of 1kg of limestone CAO is calculated at 48%. In the end, the estimated formula for CO2 emissions is: CO2 emissions = limestone consumption*0.38+e = 271kg+501kg = 772kg. CO2。由于CO2排放量一般不做检测，排放量按下列公式计算。 CO2生成主要产生于燃料、燃煤等化石能源的燃烧以及水泥生产原料中的石灰石分解。（1）化石能源燃烧的CO2排放量计算如下：E=3.67FQka。E为CO2的排放量，kg；F为燃料的消耗量，kg；Q为燃料发热量，MJ/kg；k为燃料的碳排放系数；a为燃料的碳氧化率。（2）水泥生产过程中，原料石灰石的化学反应产生大量的CO2其化学反应见式：CaCO3→CaO+CO2↑。1kg石灰石的CaO的百分含量按48%计算。最后得CO2排放量的估算公式为：CO2排放量=石灰石消耗量*0.38+E=271kg+501kg=772kg。 cement, ordinary portland cement, 42.5MPa Output 1000.0 1000.0 42.5 Ordinary silicate cement 42.5普通硅酸盐水泥
