Abstract


Abstract
In recent years, the use of inhibitors in producing high performance concrete has increased significantly as a result of chloride and sulfate attacks. The present inhibitors in market are toxic to the environment. Hence, the objective of the present investigation was to study a novel, eco-friendly and a hydrophobic green plant extracts’ inhibitor (rice husks) and study the effects of it on compression strength of reinforced concrete. The inhibitor above was added to the concrete mix in dosages (1, 2 and 3% by weight of cement); and studied the effect of using rice husks as corrosion inhibitor admixture for concrete, submerged partially in electrolyte solution (water + sodium chloride in 3.5% concentration). The results showed that the green inhibitor does not have any effect on compressive strength; only 3% green inhibitor caused increases little bit in strength, but the effect of this inhibitor on corrosion rate very large, when we increased the concentration of green inhibitor, the concrete samples became more resistance to corrosion.


Keywords: Rice husks, compressive strength, corrosion rate, FTIR
