Abstract: TViscosity Modifying Admixtures (VMA), chemical based admixtures, used to increase the viscosity of cement based grouts. Usage of natural materials as admixtures in VMA is much needed in current scenario. Present work aims in using Moringa pterygosperma (gum of drumstick tree) as an admixture. Studies were conducted by adding 1-10g of Moringa pterygosperma with the mass of water and maintaining water-cement ratio (w/c) of 0.4 with 1:3 mix ratios. The resultant cement mortar is studied for Compressive strength, Split tensile and rapid chloride penetration test. Tests conducted were compared with 28-days cured conventional specimen which evidentially proved that use of natural VMA increased compressive and tensile strength by 11.2% and 47.42% respectively. Appreciable improvement in penetration values were found out in the experiment.
