Conclusions
The porosity of kaolinized batches containing 85% chamotte (water absorption not more than 5%) and 15% Druzhkov clay after firing at 1500°C is reduced to 10–8% by volume as a result of the use of surface active additives, combined with talc-magnesite or bentonite.
One of the decisive factors in obtaining high-density products is an adequate milling of the combined milled mixture of chamotte and clay.
