Jul 08, 2021 Fly ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials.

A large number of fly ash without treatment will produce dust and pollute the atmosphere; if discharged into the water system, it will cause River silting, and the toxic chemicals in it will also cause harm to human body and biology. In addition, fly ash can be used as admixture of concrete.
15. Coloring Admixtures Coloring admixtures are the pigments which produce color in the finished concrete. The admixtures used to produce color should not affect the concrete strength. Generally coloring admixtures are added to cement in a ball mill, then colored cement can be obtained which can be used for making colored concrete.
Fly ash as a mineral admixture should conform to IS: 3812. Such a material is available in the finer streams of Electro Static Precipitators fitted to the power generation system.
