Will this concrete help build a better bridge?

When a reinforced concrete bridge deck is subjected to freeze-thaw cycles and de-icing salts over a number of years, the ensuing deterioration drastically reduces the structure’s service life and results in costly maintenance or early replacement. In such severe environments, high-performance concrete (HPC) is often required because of its superior strength and low permeability. Unfortunately, HPC also has a tendency to crack prematurely if not properly cured.
