The raw materials used in the production of ordinary portland cement at the Chongqing Xiaonanhai Cement Plant are limestone, clay, iron ore, and gypsum. The consumption of raw materials per ton of ordinary portland cement is 0.615 tons of limestone, 0.283 tons of clay, 0.213 tons of iron ore, and 0.286 tons of gypsum, without considering the utilization of industrial waste.小南海水泥厂干法旋窑生产工艺生产普通硅酸盐水泥。重庆小南海水泥厂普通硅酸盐水泥的生产原料采用石灰石、粘土、铁矿及石膏，1t普通硅酸盐水泥料耗为石灰石0.615t、粘土0.283t、铁矿0.213t、石膏0.286t，不考虑工业废渣的利用。11Chongqing Xiaonanhai Cement Plant重庆小南海水泥厂The ordinary portland cement produced by Chongqing Xiaonanhai Cement Plant is mainly utilized in the construction industry for creating standard concrete mixtures. This specific type of cement is appropriate for the construction of buildings, infrastructure, and other projects requiring a strong and durable concrete. The production does not involve the use of industrial waste materials, therefore it is essential for applications demanding a high degree of purity in cement composition.由重庆小南海水泥厂生产的普通硅酸盐水泥主要用于建筑行业，用于制备标准混凝土混合料。这种特定类型的水泥适用于建筑、基础设施和需要强度和耐用性的其他工程项目的施工。生产不涉及工业废物的使用，因此对于要求水泥成分具有高纯度的应用至关重要。The system boundaries range from raw material mining to cement manufacturing. The functional unit is the amount of ordinary Portland cement required for 1 m3 of concrete. The standard concrete ratio of 1m3 is: 365kg cement, 601.2kg sand, 1378.9kg aggregate.系统边界为原料开采到水泥制造。功能单位为1m3混凝土所需要的普通硅酸盐水泥的量。1m3标准混凝土配比为：365kg水泥、601.2kg砂、1378.9kg集料。LCI resultNone无None无None无None无Accumulation of process data for raw material mining and cement manufacturing units.原料开采与水泥制造单元过程数据累加。None无熊文强 & 王熙.

It has three 3X11m vertical kiln cement production lines and two 350,000-ton new dry process rotary kiln production lines. The products are ordinary Portland cement and composite Portland cement.重庆小南海水泥厂是 2005年重庆市经委确定的首批清洁生产试点企业之一，拥用3条3X11m机立窑水泥生产线，2条35万t新型干法旋窑生产线。产品为普通硅酸盐水泥及复合硅酸盐水泥。While using the LCI data from Chongqing Xiaonanhai Cement Plant, ensure to include the accumulative process data for both raw material extraction and cement manufacturing within the system boundaries. The system boundaries begin from raw material extraction and end at the manufacturing of the cement itself. When modeling the use phase or conducting further analysis, consider that the functional unit represents the amount of ordinary portland cement necessary for 1 m3 of standard concrete mix. The standard mix ratio includes 365 kg of cement, 601.2 kg of sand, and 1378.9 kg of aggregate. Recycling or the utilization of industrial by-products should not be considered in this LCI as the dataset does not account for such processes.在使用重庆小南海水泥厂的生命周期评估（LCI）数据时，请确保在系统边界内包括原料开采和水泥制造的累积过程数据。系统边界从原料开采开始，到水泥制造结束。在建模使用阶段或进行进一步分析时，考虑功能单位代表1立方米标准混凝土混合物所需的普通硅酸盐水泥量。标准混合比包括365公斤的水泥，601.2公斤的砂和1378.9公斤的骨料。由于数据集未计算此类过程，不应考虑回收或利用工业副产品。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+08:002024-04-20T14:41:13.614123+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=7f815c8a-bacb-40be-9580-751a79cdacb0&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 carbonateInput643.8356164643.8356164Limestone石灰石clayInput279.4520548279.4520548Clay粘土iron oreInput221.9178082221.9178082Iron ore铁矿gypsumInput282.1917808282.1917808Gupsum石膏hard coalInput225.6164384225.6164384Raw coal原煤crude oil; 42.3 MJ/kgInput12.7397260312.73972603Crude oil原油natural gas; 44.1 MJ/kgInput1.0876712331.087671233Natural gas天然气carbon dioxide (fossil)Output711.6438356711.6438356CO2CO2sulfur dioxideOutput1.5479452051.547945205SO2SO2Nitrogen oxidesOutput1.4794520551.479452055NOXNOxcarbon monoxide (fossil)Output1.7424657531.742465753COCOcement, ordinary portland cementOutput1000.01000.0Ordinary Portland Cement普通硅酸盐水泥
