Major role of fly ash in concrete structures
Fly ash is a very fine-particulate material that looks and feels like talcum powder and can be a tan to gray color,
depending on its source. It is classified as a pozzolan and with its high silica content is used by concrete producers
as a component in the range of 10 to 25% of the cementitious portion of concrete mixtures (iv). Fly ash forms calcium
silica hydrate (cementitious material) in addition to that produced by hydration of portland cement.Here’s where its
importance of fly ash in concrete becomes clear: More than 75% of all concrete is made with fly ash, fly ash is specified
for all concrete structures. And the concrete industry is only one of the important entities using this abundant waste material
