The present research work involved cleaning contaminated acid resistance refractory brick waste. The waste brick was crushed to 30 mm size granules, and further ground by hammer milling to 1mm. The oversized powder (+0.355 mm) was subjected to high energy ball milling to produce nano-powder with particles sizes ranging from 45 to 51nm. Each powder batch was made up of three components; brick waste nano-powder, coarse over-sized waste brick powder, and 75 micron-sized local Sebha Kaolin clay. The pressed powder batches were then dried at a temperature of 110˚C before being fired at 1000, 1300, and 1500˚C to produce shaped final products. Characterization of starting refractory waste bricks, waste coarse powder, and waste nano-powder using the technique of X –Ray Diffraction (XRD) was carried out. The work also involved the measurement of thermal properties of sintered final products. Melting of a glassy phase was observed at the firing temperature of 1500˚C. The presence of this phase had a negative effect on thermal properties. Hence, based on the obtained results of the present research work, this limited the recommended maximum working temperature of the produced bricks to 1300˚C. The inclusion of 30% of nano-sized powder particles as a component in the refractory powder batches had a positive effect on thermal conductivity of the final shaped products fired at 1300˚C. This would mean that the most suitable refractory brick powder batch is 35: 30 : 35 with the local Sebha kaolin clay playing the role as a good binding material. |
