Electrochemical Corrosion Behaviour of Concretes

The analysis of results showed that concrete at 50% IOT replacement of river sand has close trend in terms of corrosion current, EIS, concrete resistivity and polarization resistance (Rp). It seems that there is a potential for the use of IOT as a sustainable and environmentally-friendly in replacing sand for concrete, especially at a 50% replacement level in high strength concrete to resist corrosion.
