THERMAL CHARACTERIZATION OF KAOLINITIC CLAY

2021年3月22日  clay. 1. INTRODUCTION The kaolin obtained from natural sources is impure. Thus, it is necessary to transform it from a non-active material into reactive metakaolin (MK) by heating. The process is possible by the calcination which causes water loss and its transformation into meta-kaolinite [1], an aluminium silicate with a disordere d structure.

Potential of Selected South African Kaolinite Clays for

2020年4月14日  Kaolinite clays produce reactive minerals when calcined to around 800 °C [ 12 ]. The use of calcined kaolinite clay in concrete reduces the amount of energy used in the production of clinker and CO 2 emissions. Energy saving occurs because the calcination temperature of clays is lower than that of clinker and they are also easy to grind.
