Wide-range optical pH imaging of cementitious materials exposed to chemically corrosive environments

Wide-range optical pH imaging of cementitious materials exposed to chemically corrosive environments

The pH of concrete-based material is a key parameter for the assessment of its stability and durability, since a change in pH is usually associated with major types of chemical degradation such as carbonation, leaching and acid attacks. Conventional surface pH measurements with potentiometric flat s...
