Notes:
The simultaneous effect of raw materials (A, B and C) on physical andtechnological properties of brick compositions was studied. This investigation was carried outusing the statistical design of mixture experiments. Ten mixtures of three raw materials wereselected and used in the experiments design. Those mixtures were processed under conditionssimilar to those found in the ceramics industry. Fired body characterisation results were thenused to iteratively calculate statistically significant and valid regression equations (traceplots), relating linear firing shrinkage, open porosity, fired bending strength and waterabsorption with the proportions of raw materials. The microstructures of some selectedsamples were studied using scanning electron microscopy. Mixtures with high clay B contentswere most adequate to produce, under constant processing conditions, a brick with specifiedproperties. The microstructures are characterized by a low closed porosity and absence ofvitreous phase
