Concrete is a mixture of aggregates and cementing materials that hydrate with the existence of water. Compressive strength of concrete is mainly controlled by the weaker component, which is the adhesion medium, cement. Accordingly, the substitution of cement for fly ash is controlled by the compressive strength that fly ash can produce.
