The steel–concrete interface | SpringerLink
27/2/2017· For steel already scale-free, increasingly finer surface finishes do decrease the amount of effective, exposed steel surface area [54, 55]. Furthermore, abrasive blasting also affects the extent to which individual features on the metal side, such as microscopic occluded regions, may be present.
