Coal ash is the less notorious byproduct of coal-fired power plants. It’s the residual solid waste that comes from burning coal. Recently reported in the journal Cement and Concrete Composites, their discovery is a method for turning waste ash into a special concrete additive that helps to fortify its internal structure by promoting a uniform hardening process from the inside out.

Ash Coal english

Coal ash is the mineral residue that is obtained as a byproduct of the coustion of coal for the production of electricity. Two types of coal ash are obtained: Fly ash , which constitutes 85% – 90% of the overall ash, is a fine, light gray powder made up of glassy spheres from sub-micron to more than 100 microns in size, (98% smaller than 75 microns; 70% – 80% smaller than 45 microns).

Fly ash - Wikipedia

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal coustion 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 coustion chaer (commonly called a firebox) is
