Industrial Production and Application in LCCs of Bauxite-Based Homogenized Grogs

Abstract:

The Bauxite-based Homogenized Grog (BHG) was industrial producted using bauxite with about 70 wt.% Al₂O₃ as starting materials and its properties were tested. Through comparing with high-grade bauxite clinker, the applications in LCCs of BHG and bauxite clinker were discussed. The results showed that the BHG with mullite as chief phase, with consistent components and structure and properties using middle or low grade bauxite as starting materials can been prepared industrially by homogenization process, vacuum-extrusion moulding and high-temperature sintering method. It also resulted that the BHG can replace competently high-grade bauxite clinker to apply in LCCs as coarses and the LCCs with BHG as coarses have more outstanding properties.
