| Use advice for data set | Users of this data set should take note that the Life Cycle Assessment is based on the specific resource and energy consumption profiles associated with the shaft kiln production technique at Guangzhou Shijing Cement Plant, as calculated by Di Xianghua. The functional unit for assessment is 1kg of 32.5MPa ordinary Portland cement. The scope of the study includes the stages from cement raw material mining to storage, excluding the consideration of industrial solid waste (slag and fly ash) as resource consumption, therefore not accounting for any pollutant emissions from these materials. When applying this data to other scenarios, it is crucial to adjust for technological differences if the processes differ significantly from the Guanzhou Shijing method. |
| Technical purpose of product or process | The described data set pertains to the production of ordinary Portland cement with a compressive strength of 32.5MPa using a traditional shaft kiln method at the Guangzhou Shijing Cement Plant. This production process uses mixed solid wastes, specifically slag and fly ash, as part of the raw materials. This type of cement is typically used in construction for a variety of structural applications where such strength classification is sufficient. |
