FlyAsh - NETZSCH Mahlen & Dispergieren

Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick.
