the fly ash as the sole cementing material (Cross 2005). In addition to providing an indication of the mineralogy and reactivity of the fly ash, the calcium content is also useful in predicting how effective the fly ash will be in terms of reducing the heat of hydration (Thomas 1995), controlling expansion due to alkalisilica reaction (Shehata

The principal difference is the point of feeding fly ash in VRM systems. VRMs have builtin highefficiency separators. Fly ash, being a naturally fine product, can bypass the mill and be fed to the separator at the mill. The roller press and ball mill combination is also being adopted in a variety of ways to make cement.

Highenergy mill (HEM) has a wide application in material preparation, activation and synthesis. In the present study, fly ash was selected to be milled by HEM under the speed of 700 rpm and the balltopowder ratio of 10:1 by weight, but varied periods of milling time. The changes in physical and morphology properties of the milled fly ash were determined using BET analysis and scanning ...
