Studying effect of addition green inhibitor on compression strength of reinforced concrete

Abstract

In recent years the use of inhibitors in producing high-performance concrete has increased significantly to mitigate chloride and sulphate attacks. The present inhibitors in the market are toxic to the environment. Hence, the objective of the present investigation was to study a novel, eco-friendly and green waste plant (orange peel) extracts inhibitor and study its effects on compression strength of reinforced concrete. This inhibitor was added to the concrete mix with concentrations of 1% and 3% by weight of cement with two types of superplasticizers. Results showed that the tested penetrating type corrosion inhibitor as an admixture of the concrete samples did not impair on compressive strength, but with one of the superplasticizers showed higher (acceptable) values compared to the other type of superplasticizer due to the difference between their ability in reducing the ratio of water of the concrete samples.
