This paper explores how using carbonated mineral products in cement can help reduce carbon emissions and improve durability. It focuses on replacing part of the cement with mineral carbonated biomass fly ash (BFA) and assesses its environmental benefits. The study found that incorporating 20% BFA could lower cement’s carbon footprint by 33% per year. Machine learning models predicted CO2 absorption and energy use, showing better efficiency at larger scales. However, challenges remain, such as lower material strength and limitations in data modelling. Overall, the research highlights BFA’s potential for greener cement but calls for further optimisation.
