Effect of Corrosion Inhibitor on Compressive Strength and Corrosion Resisting Properties of Blended Concrete

Abstract

Use of blended concrete in the construction industry increased to reduce the cost and environmental effect. Present these paper presents Compressive Strength & corrosion resistance of blended concrete with partial replacement of cement by different percentages of marble powder & Fly-ash i.e., (5%MP+5%FA), (7.5%MP+7.5%FA) & (10%MP+10%FA). The strength increased at (7.5%MP+7.5%FA). Corrosion inhibitor (calcium nitrate) 1%, 2% and 3% added to normal concrete and (7.5%MP+7.5%FA) there is small decrease of strength but corrosion resistance shows better results at 2% of corrosion inhibitor added. The corrosion resistance is evaluated based on the performance of concrete from weight loss measurement test.
