Abstract:
Pozzolans, fly ash in particular, have been around for a long time. But not until the late 1930s was fly ash technically discussed as a viable ingredient in concrete. Since then its use has been sporadic and selective. Dams have been built with concrete containing fly ash and test strips of pavement have been placed, but the concrete industry as a whole has been slow in accepting it. In the author’s opinion, the reasons for this were lack of availability of high-quality consistent material, lack of adequate technology, and sales programs based on cutting cement.
