Effect of Fly Ash on Strength of Concrete

Oct 26, 2019 · Abstract. An enormous amount of fly ash is generated in thermal power plants in India, which affects the environment and living organism. By means of fly ash in concrete in place of cement reduces the consumption of natural resources, diminishes the environmental pollution and also economical as replacing the cement which is costlier by the fly ash.

Fly Ash Properties and Uses

Fly ash closely resembles volcanic ashes used in production of the earliest known hydraulic cements about 2,300 years ago. Those cements were made near the small Italian town of Pozzuoli – which later gave its name to the term pozzolan. A pozzolan is a siliceous/aluminous material that, when mixed with lime and water, forms a cementitious compound. Fly ash is the best known, and one of the ...
