Part I: Characterizing blended cement materials. Cover: Processed scanning electron microscopic image of the fly ash-blended cement (256 µm by 200 µm) studied in this report. The orange particles are fly ash, and the rest are cement constituents. Some of the orange fly ash particles are not particularly round, as is usual for fly ash, which may be a result of the fly ash-cement intergrinding process.
