Bolts and anchor rods that are very high strength ($F_u$ > 150ksi) are not supposed to be galvanized. This is because of concerns about hydrogen embrittlement. This includes ASTM A 490 bolts and ASTM A 354 Gr. BD anchor rods.
The project in question has very high lateral loads and is outdoors. Typical ASTM F 1554 Gr. 105 anchor rods end up being very large in diameter. This is why ASTM A 354 Gr. BD rods (2.5 inch diameter) are specified. There is no space for more anchor rods.
Since the project is outdoors, a corrosion protection coating is required. The only coatings that can be used are Zinc/Aluminum coatings such as ASTM F 1136 Grade 3.
There is a history of aluminum not being used in contact with concrete because of corrosion concerns. This seems to be specifically with solid aluminum.
Do I need to be concerned with the aluminum content of this coating reacting with the concrete that the anchor rods are embedded in?
