Abstract: This paper reports the results obtained in the study of thermal activation of kaolinite used as a hydraulic agent in old aerial lime mixtures. This study has been carried out in order to obtain a better knowledge of the old lime mixtures containing kaolinite and to set up a ‘modern’ hydraulic additive with improved qualities. In particular, this paper deals with changes that could have happened in the kaolinite structure when this mineral was burnt inside the old lime furnaces. With this aim in mind, a large number of bibliographic references have been studied. Results obtained show that the kaolin could have burnt in the same furnaces used for the lime production but that these two materials may have burnt separately and probably at different temperatures.
