Use advice for data set When utilizing this LCA data, consider the substitution of fly ash in place of traditional raw materials which contributes to resource conservation and environmental benefits. Appropriate allocation methods should be applied when considering recycled content and potential avoided burdens. The system boundary of 'from cradle to gate' should be adhered to, involving raw material acquisition, transportation, clinker production process, as well as considering the impacts of the upstream power generation and avoided ash disposal.
Technical purpose of product or process The cement clinker product with a compressive strength of 52.5MPa utilizing 4% fly ash as a partial raw material substitute is intended for use in the construction industry, specifically for creating concrete mixtures with enhanced performance characteristics such as durability and reduced environmental impact.

Mathematical model
Model description Cement clinker with a strength of 1 ton of 52.5MPa is selected as the functional unit. The study selects the system boundary of "from cradle to gate". The natural mineral production cement clinker product system includes the acquisition, transportation and cement clinker production process; the comprehensive utilization of fly ash to produce cement clinker system boundary also includes the upstream power generation system. and avoid the fly ash accumulation and disposal process.
