(portland cement, blended cement, fly ash, slag, silica fume, and natural pozzolans). The water-cementitious material ratio selected for mix design must be the lowest value required to meet anticipated exposure conditions. Tables 9-1 and 9-2 show requirements for various expo-sure conditions. When durability does not control, the water-cementi-
