Abstract

The effect of corrosion inhibiting properties on concrete and mortar is investigated experimentally. The mortar was prepared by using Ordinary Portland Cement (OPC) and Pozzolanic Portland Cement (PPC). Based on the efficiency obtained, OPC was used to prepare concrete. Based on the literatures, Azadirachta indica (Neem) is in two forms, one as powder and another as solution and acting as a Green Corrosion Inhibitor (GCI). The efficiency of two forms of GCI was compared. The physical properties such as consistency and initial setting time have been evaluated by mortar paste, and the mechanical properties such as compressive strength and split tensile strength have been tested by casting mortar cubes, concrete cubes, and cylinders. The addition of GCI in the form of powder decreases the compressive strength due to drought resistance of the neem powder, whereas solution shows the best result due to hydroscopic property of ethanol. Therefore, extracts of plants and natural products are used to achieve cheap, environmentally acceptable, abundant source, readily available and effective molecules having very high inhibition effectiveness and low or zero ecological impact.
