EFFECT OF CURING METHODS ON THE PROPERTY OF RED MUD BASED GEOPOLYMER MORTAR

The aim of this investigation is to carry out the synthesis and performance studies on both heat cured and ambient cured mortar. Compressive strength is an important aspect of hardened mortar. Along with the compressive strength, tensile strength and modulus of elasticity of mortar have been discussed. Strength of thermally cured mortar improved with molarity whereas ambient cured mortar possessed better strength at lower molarity. All mortars with 30% red mud exhibited maximum strength. Highest strength obtained was 11.8 MPa for ambient cured mortar with 30% red mud and 6M molarity. Tensile strength followed similar pattern as the compressive strength. Ambient cured mortars were found to be stiffer than the thermally cured ones.
