Project description

Major steps have been taken with concrete reinforcing steel to address corrosion issues in Utah’s bridges. However, improving bridge deck concrete should remain a priority to extend concrete bridge deck service life. Concrete surface resistivity and bulk resistivity, are very easy to implement, non-destructive tests which can identify several important parameters, including concrete permeability and can potentially be correlated to applied tension loads, pore size distribution, internal relative humidity and accurately detect setting time.
