Abstract

Fly ash (FA) F low reactivity, slow hydration reaction and low early strength, restricted its industrial usage to less than 25 wt %. Ash properties were modified by mechanical activation to achieve higher added value product. The activation depends on the equipment type and their particle size range of milling. This paper reviewed the milling equipment effect on particle size, surface properties, and chemical compositions of activated ash. Increasing in the surface area, pozzolana activity and the reduction of crystalline dense layers of fly ash F, leading to microstructure and structural variations which raised  the ash industrial applications.
