2. Fly Ash Properties. Fly ash is a complex material, being a byproduct resulting from the combustion of various coals with high contents of minerals [4,21,22,23].Consequently, fly ash is rich in metallic oxides, in the order SiO 2 > Al 2 O 3 > Fe 2 O 3 > CaO > MgO > K 2 O and large amount of unburned carbon. Furthermore, fly ash contains trace elements that can have a negative impact on the ...

Figure 31: Fly ash improves workability for pavement concrete. Decreased water demand. The replacement of cement by fly ash reduces the water demand for a given slump. When fly ash is used at about 20 percent of the total cementitious, water demand is reduced by approximately 10 percent. Higher fly ash contents will yield higher water reductions.

Most fly ash sources are capable of meeting the gradation (minus .075 mm) requirements and other pertinent physical (nonplastic) and chemical (organic content) requirements of mineral filler specifications. Fly ash must be in a dry form for use as a mineral filler. Fly ash that is collected dry and stored in silos requires no additional processing.

FA, or pulverised fuel ash, is a byproduct of coalfired power plants and is used as a mineral additive in cement and concrete. Fig. 1 shows a typical layout of a coalburning generating station. Pulverized coal is blown into the burning zone of the furnace, where its combustible constituents, mainly carbon, hydrogen, and oxygen, ignite at around 1500 °C (2700°F).

Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from µm to 300 µm. The major consequence of the rapid cooling is that few minerals have time to crystallize, and that ...
