Mineral Admixture - an overview ScienceDirect Topics

Mineral Admixtures. Mineral admixtures (fly ash, silica fume (SF), and slags) are usually added to concrete in larger amounts to enhance the workability of fresh concrete; to improve resistance of concrete to thermal cracking, alkali-aggregate expansion, and sulfate attack; and to enable a reduction in cement content. Fly ash.
