Discussion on Several Problems in the Study of Corrosion Mechanism of Steel - Concrete Composite Beams

摘要

It's of great practical significance to improve the durability of steel-concrete composite beam structures. The deterioration of steel-concrete composite beams includes stud rust, reinforcement corrosion, corrosion of the steel beams and concrete performance degradation, which are caused by a number of factors. The corrosion mechanism of composite beams is discussed, and some basic issues remain to be solved in this area are analyzed in the paper. Besides, some research directions in the future are put forward.
