Pulverized fly ash berasal dari limbah industri yang sudah melalui proses pengolahan penghalusan dan penyaringan dari zat–zat karbon yang merusak beton dengan teknologi modern untuk mengurangi kandungan karbon, sehingga ikatan agregat dalam campuran beton akan homogen, solid, dan kuat.
L. Black, in Sustainability of Construction Materials (Second Edition), 2016. 17.3.1 Origin of fly ash, composition and physical properties. Fly ash, also known as pulverised fuel ash or PFA in the United Kingdom, is a by-product of the combustion of pulverised coal in thermal power plants. The ash is composed of the fine particles that are driven out of the boiler with the flue gases, before ...
Fly ash or Pulverised fuel ash. Fly ash, also known as pulverised fuel ash (pfa) is the ash resulting from the burning of pulverised coal in coal-fired electricity power stations. The ash is very fine and it is removed from the flue gases by electrostatic precipitators.
ORIGIN. The fly ash produced from the burning of pulverized coal in a coal-fired boiler is a fine-grained, powdery particulate material that is carried off in the flue gas and usually collected from the flue gas by means of electrostatic precipitators, baghouses, or mechanical collection devices such as cyclones.
Fly ash can also mean ash from furnaces other than coal-fired power station furnaces. However it is usual to refer to the type of burning involved to create it, e.g. incinerator ash, paper sludge fly ash. This distinction is important as fly ash from other furnaces have very different properties from the ash produced at coal-fired power stations.

Pulverized fly ash (PFA) is produced about 500 billions tons every year in the world in a result of coals combustion. Most of the fly ash collected in power plants is disposed by deposition in landfills, situated as a rule near big cities with well developed infrastructure and high cost of land.

Fly ash in concrete is widely used across the U.S. to the strength of concrete. Fly ash suppliers such as CEMEX use it to improve workability of fresh concrete and reduce water demand, shrinkage and permeability of the finished product.
Pulverized fuel ash commonly known as fly ash is a useful by-product from thermal power stations using pulverized coal as fiel and has considerable pozzolonic activity. This national resource has been gainfully utilized for manufacture of Pulverized fuel ash-lime bricks as a supplement to common burnt clay building bricks leading to conservation
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, 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 called bottom ash.
In general, pulverised coal combustion results in approximately 70–90% fly ash, and the remainder is coarser bottom ash or boiler slag. Bottom ash is a coarse material and falls to the bottom of the furnace. Fly ash is finer than bottom ash and is carried with the flue gas along the combustion process.
The Effective Collection of Fly Ash At Pulverized Coal-Fired Plants The relationship between sulfur in coal, boiler exit gas temperature, and the carbon por tion of fly ash have a major effect on the electrical properties of fly ash. Whether effective
Fly ash from pulverized coal power plants can be a valuable mineral admixture in concrete and other high-value applications. However, plant technologies in use today to reduce NOx emissions and enhance electrostatic precipitator performance make meeting applicable quality standards an ongoing challenge.
