Jun 25, 2019  Hence, a method of replacing fine aggregate with fly ash was proposed [24–30]. Because fly ash replaces part of the fine aggregate, part of the fly ash act as a cementitious material to fill pores and increase the compactness, while the remaining produce a volcanic ash effect, which is attributed to the presence of SiO 2 and Al 2 O 3.
