Furthermore. Production costs can be reduced by the partial replacement of cement with fly ash. Generally, the amount of fly ash to be added ranges from 15 to 35 wt% and can even reach 70 wt% for concrete in constructions such as walls, parking lots, and pavements. Yet, it can reach 80 wt% in autoclaved aerated concrete (Dilmore, 2001).
