This summary report shares the findings of an Exploratory Advanced Research (EAR) Program project that investigated strategies for expanding the use of fly ash (FA) in concrete production. With an unprecedented massive concrete and FA dataset collection of 40,000 data records, the team conducted a series of experiments that used advanced material characterizations, machine-learning techniques, and numerical simulations to uncover the fundamental attributes governing the reactivity of FA and its suitability as an ordinary portland cement replacement. This work aimed to enhance the use of FA for producing more sustainable concrete.
