Fly Ash for Concrete: Properties, Uses, Advantages

Fly ash mainly contains silica (SiO 2), calcium oxide (CaO), alumina oxide (Al 2 O 3) and ferric oxide (Fe 2 O 3). Its components vary depending upon the type of coal burnt. Fly ash is produced by rapid cooling and solidification of molten ash; hence a large portion of fly ash particles are in the amorphous state.
