In this discussion of how the unique properties of fly ash affect the properties of concrete containing fly ash as an ingredient, the following points are made: (1) fly ash reacts with the lime from the hydration of portland cement to produce strong, durable cementitious compounds; (2) fly ash contributes to increased plasticity of the concrete, usually with less mixing water, improving placing and finishing; (3) fly ash improves the resistance of concrete to sulfate attack regardless of the type of cement used; and (4) fly ash reduces the heat of hydration. It is also pointed out that quality control both of the fly ash itself and of its handling and batching is essential. The specifications and several mix designs for type I-P portland-pozzolan cement are presented.
