Lateritic bauxite is classified into six major types on the basis of conditions of weathering and deposit age [7]. The karst bauxite is composed of boehmite and diaspore as aluminous mineral and kaolinite as silicate mineral. The karst bauxite is widely distributed in Northern Asia and Eastern Europe. The differences in composition of both

The disposal of bauxite tailings (BT) remains a significant challenge for the global aluminum industry. However, its application in Limestone Calcined Clay Cement (LC 3) systems shows immense potential.Despite this, the optimal calcination temperature for BT and its effects on LC 3 performance have yet to be clearly defined. To address this gap, the study employs …
