| Abstract:At present, the white mud from chemical recovery plant has not been effectively utilized, its piling up not only occuppies a lot of land, but also causes serious environment pollution. In order to solve the problem, using the white mud and shale to product brick was studied. The chemical composition and granularity of the white mud were tested and analyzed. White mud was directly added to shale in different ratio then the solid bricks were sintered. And the effects of ratio of raw materials and the firing system on compressive strength, water absorption, shrinkage of the product were studied. The results showed that the properties of the brick accord with the national standard of Fired Common bricks(GB5101—2003) when the mixing amount of white mud is 15% to 27%, the sintering temperature is 900℃ to 1100℃ and insulation is 1 to 3 h. This is significance for the utilization of white mud and reducing environmental pollution. |
