Abstract:

This study is devoted to explore the possibility of using two clays in the south of Senegal in the local industry. The chemical and mineralogical compositions, their density and specific areas are used to classify them as kaolino-illite clays or kaolini-smectite. Thes structural phases are detected during tehrmal analyzes. The mechanical properties remain low and the addition of an organic biopolymer increases the flexural strength from 28 % to 1000°C even if it does not reach the standard bricks and tiles. Prospects are the addition of fluxes potassic and sodic to accebtuate the densification and to lower the temperature of cooking.

Keywords:

Silicate ceramics, clay minerals, biopolymer, unidirectional pressing, consolidation.
