2] phase, as well as the formation of a secondary Ca-Al hydrate phase hydrocalumite and a hydrous Ca-Al sulfate phase ettringite.
There is no ettringite detected in the NaOH activated mixtures and hydrocalumite is present in the samples cured for 28 days.
Their crystallite morphology and chemical composition identify them as hydrocalumite and ettringite, even though the relative abundance and particularly the size of the lath- and needle-like ettringite crystallites are much smaller than those observed in other hydrated oil shale ashes [14].
3d), but their pore-space is filled with hydrocalumite platy crystals and crystal aggregates while no lath-shape ettringite crystals are detected.
