    kaolinite will be the most suitable clay to use because each layer is built up of a silica and alumina content that is disrupted when heated and becomes available to react with limestone. the ideal kaolinite content is 40-60 per cent in calcined clay cements, said professor scrivener. such clays are widely available in china, southeast asia, africa and the americas.



    at low temperature calcined china clay, called metakaolin, improves properties of cement based systems, reduces lime efflorescence and corrosion of concrete reinforcements, increases abrasion and chemical resistance of concrete or enhances frost-thaw resistance of tile adhesives.
