Performance of high volume fly ash concrete

An increase of fly ash fineness in HVFA concrete has a significant effect on the degree of hydration. The use of ultra-fine fly ash to produce HVFA concrete increased the mechanical and durability properties significantly compared to raw fly ash. This is primarily due to the densified microstructure created by the fine particle packing [53].

Fly ash properties, characterization, and applications: A review

Fly ash (FA) is the principal industrial waste byproduct from the burning of solid fuels. FA is a powdery solid that is constituted mostly of unburned carbon (UC), metal oxides (Si, Fe, Ca, and Al), and other inorganic substances. UC is an inexpensive source of activated carbon that plays an important role in FA adsorption capacity.
