Evaluation of Physical, Chemical Properties and Characterization Studies of Organic Inhibitor (Azadirachta Indica Gum) Using Concrete Corrosion

Abstract

The present research work mainly focused on the influence of natural admixtures using concrete with enhanced properties and to prevent the corrosion using natural inhibitors. Corrosion of reinforcement is one of the drawbacks in reinforced concrete structure to overcome corrosion problem an attempt has been made in the present investigation by use of corrosion inhibitors. The organic inhibitors extracted by water from Azadirachta indica (Gum). In this study. the effect of Azadirachta indica gum as set retarding admixture in cement pastes. The various concentrations of 0.2 mg/L to 1.6 mg/ L of the weight of cement and w/c ratio of 0.50. In the physical properties study, the inhibition efficiency was increased with increase in the concentration of inhibitors for mild steel aqueous medium the maximum concentration (1.6 mg/L). The effect of aqueous extract of (Azadirachta Indica Gum) on the corrosion inhibition of mild steel in various concentrations of 0.2 mg/L to 1.6 mg / L) solution was investigated by electrochemical study and weight-loss experiments at temperatures ranging from 303 K. The percentage of inhibition increased with the increase of the concentration of the inhibitor. At a concentration of 1.6 mg/ L, the percentage inhibition reached about 85.24% at 303 K. The SEM analysis showed that inhibitors adsorbed on mild steel surface to protect mild steel from corrosion. The aqueous extract was found to be an excellent potential corrosion inhibitor because of the high content of alkaloids. The results of inhibitors showed the natural gum has better corrosion inhibition efficiency. It is also observed that the efficiency of inhibitors depends on the exposure environment.

Moringa oleifera gum effect on blood sugar levels and rat pancreas histology induced by Streptozotocin

“…In this case, it is allegedly because Moringa gum has antioxidant activity that can react with free radical compounds (ROS) so that it can reduce damage to the structure of the pancreatic islets of Langerhans in diabetic mice. This is by research which states that Moringa gum contains phytochemical compounds including alkaloids, saponins, and oils (Annaamalai et al, 2017). Saponin acts as an antioxidant by reducing superoxide through the formation of hydroperoxide so that it can prevent lipid damage (lipid peroxidation) (Hasan et al, 2022).…”
