The 2006 fly ash use survey conducted by the Ameri- can Coal Ash Associa- tion indicates that out of the 72.4 million tons of fly ash produced annually 45% was beneficially utilized; 59% of this was used in cement and concrete applications. Concrete is the largest market for fly ash and offers the highest potential for
The term fly ash was first used in the electrical power industry ca. 1930, the first comprehensive data on its use in concrete in North America were reported in 1937 by Davis et al. [1]. The first major practical application was reported in 1948 with the publication by the United States Bureau of Reclamation if data on the use of

The use of fly ash in portland cement concrete (PCC) has many benefits and improves concrete performance in both the fresh and hardened state. Fly ash use in concrete improves the workability of plastic concrete, and the strength and durability of hardened concrete. Fly ash use is also cost effective. When fly ash is added

Information is pre- sented on the advantages and disadvantages of using fly ash in the portland cement concrete used in highway construction. Administrators, engineers, and
I am happy to know that Ash Utilization Division is publishing a book named “Fly Ash for Cement Concrete". Among several informative and useful insights contained in the book is the fact that mixing of ash gives higher strength and durability to concrete. NTPC has been imparting thrust to ash utilization strategies,.
Fly ash is used as a supplementary cementitious material (SCM) in the production of portland cement concrete. A supplementary cementitious material, when used in conjunction with portland cement, contributes to the properties of the hardened concrete through hydraulic or pozzolanic activity, or both. As such, SCM's
