Effect of Cement Replacement by Bauxite Residue on the …
Using bauxite residues in concrete has proven to be an environmentally friendly and sustainable approach. In this study, cement mass was partially replaced with bauxite residues (at 5, 10, 15, and 20%), with variations in residue diameter (300 µm, 600 µm, and 2 mm) and in liquid form. The concrete's workability, air content, density ...
