Abstract
AbstractSeven fluidized bed combustion ashes of different composition were studied as to their hydraulicity and pozzolanicity. Four of them exhibited hydraulic reactivity and hardened when mixed with water. All of them exhibited a positive effect on strength development if used as constituents of blended cements. However, the presence of significant amounts of Fe2+ and free lime in the ash, as well as excessive amounts of SO3 in the produced cement caused unsoundness associated with the decline of flexural strength after longer hydration times.
