(2025). Reducing Global Warming Potential in Cement Production: A Comparative Study of Slate and Marble Waste as Sustainable. IOP Conference Series: Earth and Environmental Science, 1536, 012028.https://doi.org/10.1088/1755-1315/1536/1/012028.1755-1315https://hdl.handle.net/11441/177178This study evaluates the reduction of Global Warming Potential (GWP) in Portland cement production through the incorporation of industrial waste from marble and slate as supplementary cementitious materials. Partial clinker substitutions between 5% and 20% were analyzed, assessing mechanical performance through compressive strength tests and environmental impact using the Life Cycle Assessment (LCA) methodology. The results demonstrated that replacing 20% of clinker with waste led to significant reductions in CO2 emissions: 16.44% for marble and 15.72% for slate. Formulations with 10% and 15% substitution showed the best balance between mechanical performance and environmental impact, meeting regulatory resistance requirements. Transportation logistics proved crucial, with longer distances negatively impacting GWP. The study concludes that reusing these residues represents a viable strategy to mitigate the environmental impacts of the cement industry, aligning with the principles of the circular economy and promoting more sustainable construction practices.application/pdf10 p.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Global warming potentialPortland cementby-productlife cycle assessmentsustainabilityinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1088/1755-1315/1536/1/012028
