Influence of nano-silica and micro-silica in the steel corrosion embedded in concrete |
|
| چکیده انگلیسی مقاله |
Corrosion of steel is one of the most important potential dangers and threats in concrete structures. Corrosion of steel embedded in reinforced concrete plays a key role in reducing the strength and durability of reinforced concrete. Several studies have proposed that alternative approaches to enhancing the performance of reinforced concrete and its resistance to corrosion. In this study, we present the results of steel corrosion embedded in reinforced concrete with micro-silica and Nano-silica particles. For testing, samples with a mixture of these particles ranging from 0 to 133 grams were generated and their performance was compared using Corrosion Potential (OCP), Electrochemical Impedance Spectroscopy (EIS), Linear Polarization (LPR), and TOEFL polarization tests. The results demonstrate that micro-silica is effective in reducing permeability of the concrete against malicious ions, but we get far satisfying results in reducing corrosion rate in concrete with Nano-silica. We also find that an equal blend of micro-silica and Nano-silica particles causes higher corrosion in reinforced concrete. |
