The potential for calcined clay, and in particular Limestone Calcined Clay Cement (LC3), to be used in concrete in Kenya was examined in this study. Locations of clay sources and existing mining infrastructure were examined for potential development. Potential sources of clay were obtained and characterized for kaolinite content and reactivity. Results showed that there is significant potential for development and use of calcined clays in Kenya. Product development issues going forward in Kenya is also discussed.
