Thermal Stability of Clays and Clay Minerals and Pozzolanic Activity

The cement and concrete industries are currently facing challenges on making their processes more sustainable without reducing the quality of their final products. This is due to the release of carbon dioxide to the environment and the high amount of energy needed in the production of cement clinker materials.Consequently two paths have been suggested such the use of renewable energies to power the rotary kilns and the use of pozzolans as supplementary cementitious materials. The former is on research and development stages but the latter is already in use and much attention is now given to clays and clay minerals due their abundant availibity . This is the basis of this master thesis research work to evaluate the potentials of some clays and clay minerals to be used as supplementary cementitious materials.
