Fly Ash

Fly ash is produced by burning powdered coal to generate electricity. Fly ash is a chemically active, finely divided mineral product high in silica, alumina and iron. Fly ash that has been burned in the process of manufacturing (in the same sense that portland cement clinker is “burned”) seeks lime. One hundred pounds of portland cement

Low CO2 Concrete | U.S. Concrete

Fly ash can replace up to 50% of the Portland cement required to manufacture concrete. Fly ash can be used to improve workability and pumpability of concrete. Due to its generally slower rate of hydration, fly ash also lowers the heat of hydration and is important in mass concrete structures, such as large foundations, bridges, dams and piers.

Cementless fly ash binder makes concrete ‘green’

 · Fly ash binder does not require the high-temperature processing of Portland cement, yet tests showed it has the same compressive strength after seven days of curing. It also requires only a small fraction of the sodium-based activation chemicals used to harden Portland cement. The results are reported in the Journal of the American Ceramic Society.

Using Fly Ash in Concrete

 · According to the Portland Cement Association, fly ash can have glass contents ranging from about 50% to 90%, depending on the coal that was used and the manufacturing process. In low-calcium fly ash (generally Type F), many of the other materials do not react in concrete – only the glass will react with water in the presence of calcium hydroxide.

Cement: Materials and manufacturing process

• Chalk is porous and often has high moisture content that leads it to its use in the ‘semi-dry/wet’ manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones.
