The amount of fly ash in mortar or concrete can thus be increased. Other features such as tightness, permeability to chloride ions, etc. are also improved. According to the author, in case of an industrial scale, finer milling of cement clinker (cement) is more preferable solution for the production of fly ash cement than grinding fly ash.

The fly ash blended mortar strength is influenced mainly by impact particle fineness and different methods of assessing the fineness of fly ash. The fineness of fly ash depends on the energy efficiency of ball mills to develop ultrafine particles and concluded that the mechanical ball mill is an effective grinding technology [24], [25], [26].
