| Abstract | The prese deals with energy savings in brick manufacture. Laboratory driven experiments with additions of Greek lignite (low rank coal) and Spanish one have been performed. In particular, co-firing of material with organic additives is performed in order to minimise the fuel con while maintaining the good quality of the brick. RD, ESEM and DTA techniques, mineralogical compositions and mineral transions were observed both in raw material and in clay= ite mixtures. For the analyses of hydrated phases, a low-cost and useful modifica a traditional diffractometer has been demonstrated. Fuel saving in brick firing was also revealed with the addition of lignite to claystone les. Due to the natural variability of both clays and lignites, the results of this study do not necessarily imply that coal-clay mixtures may always have similar performance. |
