AN EXPERIMENTAL INVESTIGATION ON THE EFFECT OF ALTERNATE WETTING AND DRYING ON THE PROPERTIES OF CONCRETE PRODUCED BY RED MUD

The main objective of this experimental investigation is to find out the effect of replacement of cement by red mud in different percentage. The different percentage replacement of cement by red mud adopted in the experimentation are 0%,2%, 4%, 6%, 8%,10%,12%,14%,16%,18%,20%. Workability testing apparatus like slump cone, compaction factor apparatus to find slump, compaction factor. The strength characteristics like compressive strength, tensile strength, flexural strength, impact strength and shear strength are found for different percentage replacement. Also effect of alternative wetting and drying for 50 cycles is found on concrete produced by replacement cement by red mud. One cycle of alternative wetting and drying means subjecting the concrete to wetness for one day and drying for one day.
