Mineralogy, chemical characteristics and stabilities of Cetylpyridinium-exchanged smectite

Clay Minerals, 2005
AbstractCP (Cetylpyridinium)-exchanged smectite was manufactured by the cationic exchange reaction of Na-smectite with CP. The adsorption behaviour shows a typical L-type isotherm representing continuous and stable adsorption in excess of twice the cation exchange capacity of CP.

Mineralogical characteristics of Ettringites synthesized from solutions and suspensions

Cement and Concrete Research, 2006
Due to the wide technical importance of Ettringite (3CaO.Al{sub 2}O{sub 3}.3CaSO{sub 4}.32H{sub 2}O) in hydrated cement based systems, four different synthesis methods were applied to get a better overview on how and under what favoring conditions Ettringite can be formed.
