Reliability Of Fly Ash Blended Concrete In Presence Of Various Admixtures: A Critical Review

Sarvesh PS Rajput, Mr. Khaitan Agrawal , D. K. Agrawal

This paper reviews the potential use of fly ash and various admixtures in partial replacement of cement. Cement has been supplemented byfly ash blendedat different concentrations of 0 percent 25 percent 35 percent and 45 percent. The key benefits of admixtures are their potential for Portland cement to be substituted and cementitious properties will still be viewed and the prices of Portland cement decreased. Very recently, rigorous air-pollution rules and standards created a surplus of byproducts for industrial usage as additional cementitious raw materials like fly ash, ricehusks and blastfurnace slagash, eggs and powdered shells, sugar cane ash, saw-dust ash etc. The application of all these waste-products not only facilitates usage of these kind of materials, even alsoenhances the concrete mix, thereby increase the characteristics of concrete's strength, durability, curing time, etc. in fresh as well as in hardened stages.
