Title: Surface Condition Effect on bond Strength of Steel Beams Embedded in Concrete
Author(s): James O. Bryson an drobert G. Mathey
Publication: Journal Proceedings
Appears on pages(s): 397-406
Abstract:Wide flange structural steel beams with different surface conditions were embedded in concrete and subjected to push-out tests to determine the effect of surface condition on the bond between concrete and steel. The surfaces of the embedded steel beams were either freshly sandblasted, sandblasted and allowed to rust, or left with normal rust and mill scale The steel beams with a sandblasted surface, and those with a sandblasted surface which was allowed to rust, developed considerably higher ultimate bond stresses than beams with normal rust and mill scale. However, at a free-end slip of 0.001 in. there was no significant difference in the bond stress for all three types of surface conditions.
