Concrete permeability is to determine how quickly oxygen, water and chloride ions will reach the layers of steel embedded in concrete, resulting in deterioration from reinforcement corrosion, carbonation, alkali-aggregate reaction, spalling of concrete, water leaking etc. Concrete cylindrical specimens were cored from a water storage structure, then the permeability test was conducted to determine the depth of water penetration and evaluate the water resistance ability as well as the life lasting of the existing structure.
Similarly, due to the presence of water, atmospheric CO2, they will result in the deterioration of protective film around the steels, allow corrosion to take place. Thus, carbonation test was performed to determine the level of degree of carbonation to estimate the remaining life of the structure.
