Abstract The most significant characteristic of corrosion inhibitors is to create chemical stability, when considering the fact that it affects concrete properties simultaneously. mild steel corrosion in 1 M HCl was studied in the presence different concentrations of Acacia longifolia, Areca catechu, Melastoma malabathricum, Elaeis guineensis and Cocos nucifera as green inhibitors and sodium nitrite (SN) as chemical inhibitor. Effects of green inhibitor utilized in this research has been investigated through conducting various tests on ordinary concrete, contaminated concrete and contaminated concrete modified with SN inhibitor and Areca catechu was found as the most efficient green inhibitor which was concluded through corrosion of mild steel and nitrogen content tests. The ordinary concrete has been contaminated by adding 5% magnesium sulphate and 5% sodium chloride by mixing water while casting. Results showed that the optimum percentage of A. catechu over concrete was 2% achieved by compressive, tensile and flexural strength test has been conducted at 7 and 28 days. Both chemical and green inhibitor showed acceptable compressive, tensile and flexural strength in contaminated concrete, while A. catechu added concrete showed superior performance when compared to SN.

Reinforced concrete is extensively used as a construction material regarding to its great compatibility between its establishing materials (Fernandez et al. 2018; Raja et al. 2016; Wu et al. 2018). Combination of steel and concrete enhances properties of constituents physically, mechanically and chemically. Construction of various types of buildings with different architecture is a result of steel reinforcement utilization (Mourya et al. 2014; Guo et al. 2019). Corrosion initiation of materials in concrete is a result of environmental exposure, which eventually leads to the deterioration of the structure. This is a critical issue that must be addressed for safety, environme
