According to Chinese cement standards (GB175-2007), SBC is a kind of ordinary portland cement (OPC), which is consist of 80-95% of Portland cement clinker and appropriate gypsum, and 5-20% of granulated BFS.This plant adopted new dry process and rotary kiln with 5 stages preheater to product SBC. The production scale was about 4000 ton/day. The content of blast furnace slag (BFS) was approximately 10%.BFS was generated as a co-product of pig iron in blast furnaces, and further treated by the means of aircooling and water-quenching. Air-cooled BFS was typically used in low-grade applications; while water-quenching BFS can be grinded with gypsum as a substitute of cementitious materials in cement production. Moreover, the utilization of BFS as admixture in SBC can improve technical properties, including strength, permeability and corrosion resistance. 基于矿渣的水泥（Slag-based cement，SBC）。按照中国水泥标准（GB175-2007），SBC是一种普通硅酸盐水泥（Ordinary portland cement，OPC），由80-95%的硅酸盐水泥熟料和适量的石膏以及5-20%的高炉矿渣组成。该工厂采用新的干法工艺和5级预热器旋转窑生产SBC。生产规模约为4000吨/天。高炉矿渣（Blast furnace slag，BFS）含量约为10％。高炉矿渣是在高炉炉内与生铁同时产生的副产品，经过空气冷却和水淬两种方式进行处理。空气冷却矿渣通常用于低级应用，而水淬矿渣则可以与石膏一起磨细作为水泥生产中的胶凝材料。此外，将矿渣用作SBC中的外加剂可以提高技术性能，包括强度、渗透性和耐腐蚀性。 15 Modern cement plants in Beijing 北京现代水泥厂 This plant adopted new dry process and rotary kiln with 5 stages preheater to product SBC. The production scale was about 4000 ton/day. The content of BFS was approximately 10%.BFS was generated as a co-product of pig iron in blast furnaces, and further treated by the means of aircooling and water-quenching. Air-cooled BFS was typically used in low-grade applications; while water-quenching BFS can be grinded with gypsum as a substitute of cementitious materials in cement production. Moreover, the utilization of BFS as admixture in SBC can improve technical properties, including strength, permeability and corrosion resistance (Song and Saraswathy, 2006). Therefore, the inventory of BFS was obtained in accordance with the allocation between pig iron and BFS based on their economic value. Moreover, the land use inventories of BFS, including land occupation and land transformation, were also considered as a benefit of preventing slag storage.

Environmental impact analysis of blast furnace slag applied to ordinary Portland cement production. Journal of Cleaner Production 120, 221–230 (2016). This dataset represents the environmental impact associated with the production of ordinary portland cement with a strength of 42.5MPa in modern cement plants in Beijing, utilizing a new dry process rotary kiln with a 5-stage preheater and a daily production capacity of 4000 tons. The dataset includes the use of mixed solid wastes and a 10% BFS admixture. When utilizing this data, it is essential to ensure that its application is consistent with the defined system boundary of cement production. Consideration of the economic allocation between pig iron and BFS, as well as land use benefits from avoided slag storage, should also be factored into the LCA. It is advised that the data only apply to similar production processes and regional conditions, as generalization to other contexts may not be accurate. 该数据集代表了北京现代水泥厂生产42.5MPa强度普通硅酸盐水泥的环境影响，采用新型干法回转窑和5级预热器，日产能力为4000吨。该数据集包括混合固废的使用和10%高炉矿渣（BFS）外加剂。在使用此数据时，必须确保其应用与水泥生产的定义系统边界一致。还应考虑生铁与BFS之间的经济分摊，以及由于避免矿渣储存而带来的土地使用效益也应计入生命周期评估。建议仅将数据应用于类似的生产过程和区域条件，因为概括到其他情境可能不准确。 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 2024-04-20T14:42:02.985989+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=36a2f64a-7eb9-468c-9aad-05176e9ecbf3&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 blast furnace slag Input 102.0 102.0 Blast furnace slag (BFS) 高炉矿渣（BFS） sandstone Input 70.2 70.2 Sandstone 砂岩 limestone, crushed, for mill Input 1080.0 1080.0 Limestone 石灰石 dolomite Input 0.000649 0.000649 Dolomite 白云石 iron ore Input 21.4 21.4 Iron ore 铁矿 ash Input 2.96 2.96 Fly ash 粉煤灰 gypsum stone (CaSO4-dihydrate) Input 76.3 76.3 Gypsum 石膏 hard coal;  26.3 MJ/kg Input 137.0 137.0 Raw coal 原煤 crude oil; 42.3 MJ/kg Input 0.0416 0.0416 Crude oil 原油 carbon dioxide (fossil) Output 744.0 744.0 CO2.
