The flash calcination technique was originally applied to chemically activate some clays such as Kaolinite and to confer pozzolanic properties. When applying this technique to Kaolin clays, a dehydroxylation process following the dehydration was noted [20,32]. This fits with the elimination of a hydroxyl bond (−OH) which occurs

    The product is termed as calcined clay. The calcination in EICL is done in rotary calciners. By controlling the calcination temperature, Metakaolin (550–900°C), Spinel (925–1050°C) or Mullite Phases (>1050°C) of calcined kaolin can be produced. Metakaolin has applications in cement, rubber, cables & ultramarine blue.Introducing activated clays on an industrial scale,With regard to the desired effect, the term “clay activation” is preferred to “clay calcination”, as a certain temperature window must be reached in the process. In this window a meta-phase of kaolin can form as an active SCM, so that the material will make a positive contribution to the final cementitious product.
