Fly ash consists primarily of oxides of silicon, aluminum iron and calcium. Magnesium, potassium, sodium, titanium, and sulfur are also present to a lesser degree. When used as a mineral admixture in concrete, fly ash is classified as either Class C or Class F …

at early ages. Compared to Class C fly ash, Class F fly ash and concrete with higher ash contents produced more pronounced reductions. Both types of ash showed a decrease in the rate of strength gain. The strengths of concrete mixtures with Class C fly ash were comparable to strengths of the concrete mixtures without fly ash at 14 days.

Fly ash or flue ash, coal ash, and also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is ...

The gravitational inertial air classifiers are widely used to produce manufactured sand and mineral fillers. Centrifugal air classifiers use secondary air flow to separate particles ranging from 100 microns to 20 microns. This air flow, as well as the diameter of the coarse-particles opening, is adjustable – for a clear, accurate cut point.
