Use of Red Mud As Addition for Portland Cement Mortars

The mix proportion of the concrete was 1.0 (Portland cement): 3.0 (fine aggregate) and the water/cement ratio was 0.6. The cement consumption was 470 kg/m3. After mixing, a vibrating table was used to ensure efficient compaction. Mortars containing distinct additions of red mud (10, 20, and 30% in weight) were prepared and analysed.
