Abstract. Kaolin (or china clay), ball clay and bentonite are the dominant 'industrial clays', and are mined for a wide variety of uses ( Table 3.1 ), which exploit the special properties of each of the three clay types: Kaolin (china clay) — is chemically inert and can be prepared as a white powder specified (in part) according to its ...

About Calcined Kaolin. While kaolin clay is widely used in its "raw" form, heat treating kaolin to produce metakaolin and other forms of calcined kaolin further increases its usability and creates an engineered product. Calcination can enhance or alter a variety of the mineral's properties to produce a material with characteristics suited ...

Limestone calcined clay cement or LC 3 is a ternary blend of clinker, calcined clay and limestone, usually with the clinker factor as low as between 0.4 to 0.5. Calcined clay acts as a source of reactive pozzolanic component of the ternary cement blend. The extent of reactivity of calcined clay depends on the kaolinite content of raw …

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.
