Since fly ash comprises the greatest fraction of coal wastes, only fly ash utilization will be addressed in this paper. The recovery and separation of the aluminum, iron, and titanium in fly ash is difficult for two reasons. First, fly ash is an extremely heterogeneous substance composed largely of an alumina-silica glass.

Fly ash in concrete contributes to a stronger, more durable, and more chemical resistant concrete mix. The main benefit of fly ash for concrete is that it not only reduces the amount of non-durable calcium hydroxide (lime), but in the process converts it into calcium silicate hydrate (CSH), which is the strongest and most durable portion of the ...

The characteristics of fly ash from the flue gas desulfurization (FGD) system are important for its reuse and are mainly depend on the desulfurization process. The physical and chemical properties of DSF ash, which refers to fly ash from the dry FGD system for the iron ore sintering process, were investigated.


A novel and cost-effective aerogel is prepared using fly ash and trona ore. • The calcination parameters are determined and the mechanism is proposed. • The silica aerogel maintains high contact angle of 151° up to 476 °C. • The silica aerogel has a large surface area of 856.2 m 2 /g after 500 °C calcination.


Highly porous and hydrophobic silica aerogel is fabricated using fly ash and trona ore as the starting materials and the cost-effective ambient pressure drying technique. The optimal calcination parameters are determined as temperature of 850 °C,

ties of fly ash, about half of which is beneficially reused, primarily in con­ struction materials (American Coal Ash Association, 2017). The remainder is stored, mostly in landfills and impound­ ments. Thus, annual fly ash production, combined with fly ash already in stor­ age, constitutes a large potential resource (Hower and others, 2017).


The stabilizers included cement, hydrated lime, and lime + fly ash. Unstabilized and stabilized glauconite were compared with unstabilized and stabilized iron ore gravel (which has been used as pavement base materials in East Texas for many years). Glauconite will absorb and hold relatively high quantities of water.

Fly ash - Wikipedia

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 …


The most widely used specification for fly ash in North America is ASTM C618 Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete (AASHTO M 295).
