In order to take advantage of the higher concrete strength, it will probably be necessary to use 0.6 in. (15.2 mm) diameter prestressing strand. Use of this strand may require adjustments at the precasting facility.

It will probably not be possible to do so for bridge decks where reducing deck thickness is not an advantage,
