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 coalfired boilers together with the flue that falls to the bottom of the boiler''s combustion chamber (commonly called a firebox) is called bottom ash.
Strength Activity Index— The test for strength activity index is used to determine whether fly ash or natural pozzolan results in an acceptable level of strength development when used with hydraulic cement in concrete. Since the test is performed with mortar, the results may not provide a direct correlation of how the fly ash or natural pozzolan will contribute to strength in concrete.
This research paper presents the first scientific attempt at a comparative study of thermal resistance of fly ash based geopolymer concrete and rubberized geopolymer concrete. In this study, rubberized fly ash based geopolymer concrete has been prepared using waste rubber tire fibres as a partial substitute for natural river sand, providing an ...
Fly Ash Used as a Pozzolan (a) General Fly ash is the finely divided residue that results from the combustion of ground or powered coal. In general, class F fly ash is produced from burning anthracite or bituminous coal and class C fly ash is produced from burning lignite or subbituminous coal.
Currently, more than 50% of the concrete placed in the contains fly ash. Dosage rates vary depending on the type of fly ash and its reactivity level. Typically, Class F fly ash is used at dosages of 15% to 25% by mass of cementitious material and Class C fly ash at 15% to 40%.

The structural effects of fly ash may be more critical, but cosmetic concerns also affect its use in concrete. It is more difficult to control the color of concrete containing fly ash than mixtures with Portland cement only. Fly ash also may cause visual inconsistencies in the finished surface, such as dark streaks from carbon particles.
Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.
