Armed concrete has been used as an effective and safe German for over 50 years in industrial, commercial systems, as well as systems protection systems. Concrete acts as a suitable substrate such as many moist soils, such as an active media environment. The ability of the concrete to accelerate moisture absorption and stability, in the long run, makes the task of implementing the earth electrode, especially for dry places. Over the years, the use of the buried electrodes in the concrete has reached full maturity. The primary concerns for dealing with large currents and preventing local rapid warming and blowing up concrete supports of embedded metal conductors have been considered. However, new concerns appeared and should be addressed by industry experts. A new concern is the long - term impact of small currents on rebar corrosion and the creation of micro-cracks around concrete connections. In this paper, the long - term impact of small currents on armed concrete has been tested and tested. Experimental results show that long - term passage of building leakage currents in the connected building system causes compressive strength reduction, reduction of concrete durability and increased penetration of reinforced concrete. The flow passage through the reinforced concrete leads to an increase in the temperature of the concrete and thus the evaporation of the water present in it, and the water vapor pressure causes the penetration of the voids of concrete to the boundary of the sand and sand. In addition, the evaporation of the concrete also leads to an increase in the electrical resistance of the reinforced concrete.
