Abstract :

The maintenance of cement ovens induces a waste discarded refractory bricks, recycling of this waste in the refractory industry may be a solution for the refractory market. In this experimental investigation, we present a study of dense refractory bricks elaborated based on waste refractory brick and kaolin at different ratio kaolin/waste refractory brick. The bricks elaborated with pressing were sintered at different temperatures ranging from 1100 up to 1400�°C. The calcined samples have undergone a series of physical, mechanical and micro structural tests. The results show that the sample with a ratio of 50% kaolin and 50% waste refractory brick fries at 1400�°C have the best mechanical and mineralogical performances.
