Abstract:
Fly ash has become an integral and important part of good, durable concrete mixtures. The methods used to design and develop these mixtures, however, have evolved over a long period of time. Because fly ash has different properties than cement, it should be utilized as a mineral admixture rather than as cement, and therefore should never be used as a cement replacement.
