Abstract
This chapter provides information on the use of coal fly ash as a pozzolan in concrete. Fly ash can be used to partially replace Portland cement in concrete, and its use provides many technical, economic, and environmental benefits. The characteristics of fly ash and the pozzolanic reaction are described. The impact of fly ash on the properties of concrete in the fresh (plastic) and hardened states are discussed, and particular emphasis is placed on explaining how fly ash can influence the long-term durability of the material. Information is also given on various applications of fly ash. The chapter also provides background information on coal bottom ash, and its use in cementitious material, concrete, and other construction applications.
