  TERMINOLOGY AND DEFINITIONS
  Aardelite. Sintered fly ash aggregate, fly ash collected
  from the flue gas of thermal power stations is dampened
  with water and mixed with coal slurry in screen mixers.
  The material is then fed into rotating pans, known as
  pelletizers, to form special pellets. These are then
  sintered at a temperature of about 1400°C. This causes
  the ash particles to coalesce, without fully melting, to
  form a lightweight aggregate. These are known under
  the commercial name of “Lytag™.”
  Aglite. It is produced in the UK by mixing clay pellets or
  shale with ground coke, passing it over a sinter strand
  hearth, then through the crushers. These are angular
  because they are crushed and graded.
  Exfoliated Vermiculite Aggregates. Vermiculite is a
  mineral of laminar formation, similar in appearance to
  mica, but unlike mica, it expands (exfoliates) rapidly
  when heated, thereby radically reducing the density.
