Thermo-mechanical behaviour of the structures of tropical clays from Togo (West Africa) fired at 500 °C, 850 °C and 1060 °C
چکیده انگلیسی

This study aims to develop new environmentally friendly construction materials that compete with modern materials in civil engineering. The paper deals in particular with tropical clays in order to develop new processing of clay based construction materials such as bricks, roof and floor tiles, for building needs in developing countries. Physical and thermo-mechanical characterisations are carried out on six tropical clay varieties from Togo (West Africa). The mechanical resistance is carried out on clay structures fired at 500 °C, 850 °C and 1060 °C. Relationships between the physical properties and the mechanical characteristics of clay structures have been established.


► Clay structures firing induces the structure dimension variation due to the shrinkage.
► Mixing clays having different dilatometric behaviour results in cracks during firing.
► Clay structures become more resistant when fired above 1060 °C.
► Around 1060 °C a clay structure is almost watertight and the water does not affect it.
