Researchers have developed a machine learning model to predict the performance of alkali-activated slag (AAS) materials, a more sustainable alternative to traditional cement. By analyzing a large dataset of over 3100 compressive strength records and 24 attributes including precursor chemistry and curing conditions, the model achieved improved predictive accuracy. A key innovation is the integration of 'average metal oxide dissociation energy' (AMODE) as a reactivity descriptor, which offers a more interpretable and effective representation than individual oxide compositions. This approach allows for the exploration of design spaces that balance strength, cost, and significantly lower CO2 emissions compared to ordinary Portland cement. AI
