| Use advice for data set | When utilizing this LCA data for the cement production process, ensure that the data corresponds accurately to the new dry process kiln technology. In modeling the cement production lifecycle, exclude the environmental load caused by the consumption of clay resources and the environmental impact due to the use of iron powder as a correction material. Consider the emissions of nitrogen oxides, sulfur dioxide, carbon dioxide, and dust in the impact assessment, as these are significant pollutants emitted from the cement production. The functional unit of the dataset is based on 1kg of cement with a 28-day compressive strength of 42.5MPa. |
| Technical purpose of product or process | The portland cement produced using the new dry process kiln technology is utilized mainly in the construction industry. It is suitable for constructing infrastructures such as buildings, highways, and bridges where a high level of durability and strength is required. The cement, with a specified 28-day compressive strength of 42.5MPa, is appropriate for structural concrete and other applications where 42.5MPa of strength is necessary. |

| Model description | The functional unit is the performance of 1kg cement with a 28-day compressive strength of 42.5MPa, that is, 1Fu=42.5kgMPa. The scope of evaluation is raw meal preparation, clinker calcination and cement preparation. The environmental load caused by the consumption of clay resources is not considered for the time being. Iron powder is an iron correction material, and its environmental impact will not be considered. The wastes considered to be emitted at the output end of the product system mainly include nitrogen oxides, sulfur dioxide, carbon dioxide and dust. |
