1. Introduction
Steel reinforced concrete structures are plays a vital role in civil infrastructures such as bridges, dams and buildings. Steel reinforcement gives structural strength, stability, durability etc. Usually the pH of concrete structures is found highly alkaline (~12.5e13.5). This high alkaline pH produces a passive film on the surface of steel and hinders the further corrosion [1]. Though, the effect of external pollutants in concretes such as chloride ions, sulphate ions and CO2 ingression affect the pH and induced the localized corrosion on the surface of steel rebar and promote the corrosion [2,3]. Prior detection and monitoring corrosion of steel in reinforced concrete structures pave the way to evaluate the lifespan of civil structures and take appropriate rehabilitation aspect. The nondestructive electrochemical corrosion monitoring methods such as galvanic potential measurement [4,5] open circuit potential measurements, linear polarization measurements and electrochemical impedance provides effective information on corrosion status [6,7] of rebar in concrete. In these methods, the rebar potential was measured with respect of standard reference electrodes like Ag/AgCl, Hg/Hg2Cl2 and Cu/CuSO4 [8]. This reference electrode is consist of liquid part of either saturated chloride or sulphate solutions and made up of glass body as one part of it. These types of glass based liquid filled reference electrodes are not suitable for insitu measurements [2] because the liquid part chloride and sulphate ions of solution leakage contaminate the concrete structure and induce the localized corrosion. In another way, most of the measurements were carried out by surface mounting techniques as per ASTM C876. This surface mounting technique may produce the erratic signal, non-reliable potential etc. due to the large distance of steel in concrete structures and outer surface. To overcome these issue, embeddable pseudo reference electrodes and solid state reference electrodes is introduced by several groups [9e16]. Pseudo reference electrode (Quasi reference electrode) is a kind of reference electrode, in which their potentials were not stable, were dependent on various factors and the potential was not usually defined (Thermodynamic equilibrium cannot exist) approximately constant under appropriate conditions. Pt and Mo wire, Ag wired covered by Ag-salt of chloride and bromide is used in this typically as pseudo reference electrode in various fields which includes of corrosion monitoring of concrete structure [14]. In solid state reference electrode, the major components of sensing materials and embodiments are solid and it is used to measure the potential of other components (i.e. to be usedpotential measurements instead of conventional reference electrodes) [17e21]. These embeddable reference electrode have numerous advantages than compared to the liquid based reference electrodes [2,22e25] and that are usable for in-situ measurements due to their, smaller size, quick response, long self-life, maintenance free use and applicable to non-aqueous medium applications.
