(2024) Finding a greener, cost-effective and colour-based partial or complete replacement to White Portland Cement for cast stone production using TOPSIS. In: Sustainable Design and Manufacturing 2023, 18 - 20 September 2023, Bari, Italy, pp. 159-16897898199815882190-3018https://doi.org/10.1007/978-981-99-8159-5_14https://dspace.lib.cranfield.ac.uk/handle/1826/23164As per recent research, the use of White Portland Cement (WPC) in the production of cast stone results in significant carbon emissions. This study aims to identify alternatives to WPC that have lower carbon emissions and are cost-effective. A literature review was performed, and data were gathered on WPC and its alternatives. Based on the literature review, five alternatives were identified. An investigation was conducted to determine the most suitable replacement for WPC based on four criteria. Automatically weighted TOPSIS which is a Multi-Criteria Decision Analysis (MCDA) was used to identify the optimal substitute for WPC. The results of the analysis were used to make a final recommendation. Overall, this study provides valuable insights into the potential substitutes for WPC in the production of cast stone, which could help to reduce carbon emissions and promote greater sustainability in the construction industry.159-168enPublisher licence4005 Civil Engineering40 Engineering33 Built Environment and Design3302 Building12 Responsible Consumption and ProductionWhite Portland CementMulti-Criteria Decision AnalysisCast stoneAlternativeBook chapter53672714377
