Secondly , protective layer thickness is too thin to protect concretereinforcedbar and reduce durability.
保护层厚度不够导致钢筋外露引起锈蚀,降低了桥梁的耐久性;

The experiment research shows that the performance of flexural member reinforced with HRB500 steel bar is the same as that of the common reinforcedconcrete members.
Owing to complicated and adverse geological conditions, the frame girder of reinforcedconcrete anchor bar was applied to reinforce the high slope of rebuilt access road.
