Since your'e embedding galvanized anchors in concrete remember that corrsion of the zink content in the hot dipped galv plating is worse the higher the pH of the concrete during the curing process. Very high pH in wet cement is normal. If this is a large job you might want to check with the concrete provider about additives to the mud that will reduce the effect. Since the reaction is between the surface of the galv and the concrete microscopic spaces may form causing an entry point for water that will make things worse over time.
