Fly ash X contains larger amount of two main oxides in comparison with ash Z and a smaller amount of other oxides. It is worth noticing that fly ash Z contains more than 45% iron oxide, more than 70% sodium oxide and greater amount of sulfur oxide (Table 1). In Table 2 and Fig. 1, phase composition of fly ashes is presented.

Cement industry emits large amount of CO2. One of the ways to reduce this emission is to use cement replacements, such as fly ash, in binding mixtures. Blends containing fly ash exhibit different properties compared to typical portland cement. In the case of very high amount of fly ash used as substitute of cement, setting and hardening …

Fly ash, also known as flue-ash, is one of the residues generated in coal combustion, which is generally captured by electrostatic precipitators in thermal power plants. The fly ash normally contains SiO 2 (40–50%), Al 2 O 3 (25–30%), CaO (4–8%), Fe 2 O 3 (3–7%), and LOI (6–22%) including unburnt carbon (3–20%).
