Effect of Additives on Consistency Limits of Red Mud Waste:A Comparative Study
Knowledge of consistency limits is considered important in predicting the engineering properties(viz.,swelling,shrinkage,strength,etc.)as well as for identifying and classifying the geomaterials.Determination of these consistency indices becomes even more imperative when selecting geomaterials(soil or waste)as a resource material for constructing earthen structures.This paper focuses on evaluating the consistency limits(or Atterbergs limits such as liquid limit,plastic limit,and plasticity index)of red mud waste admixed with oxalic acid,gypsum,sodium silicate,and the combination of fly ash and gypsum additives in different proportions,in a comprehensive way.The results show significant variations in the value of Atterbergs limits of ameliorated red mud waste vis-à-vis with that of raw waste.It has been inferred that the results reported in the study are of great help in asserting the suitability of the red mud waste in geotechnical engineering applications.
