Abstract. Fly ash ground granulated blast-furnace slag silica fume and natural pozzolans such as calcined shale calcined clay or metakaolin are materials that when used in conjunc-tion with portland or blended cement contribute to the properties of the hardened concrete through hydraulic or pozzolanic activity or both (Fig. 3-1).
