Mechanical Properties Of Experimental Analysis Of Reinforced Concrete Beams In Different Corrosion Conditions

Reinforced concrete by virtue of advantages，such as low cost,obtaining materials, projectcost. It is widely used in industrial and civil building, traffic engineering, offshore engineeringand other fields. However, the durability problems of reinforced concrete structures oftenappear in salt erosion environment. This has brought a heavy financial burden to the countryand people.This paper firstly compares and analyzes the salt spray corrosion and the drying immersioncycle test to find out the differences between them, and then further analysis the reasons tocause changes in the mechanical properties of the members. This paper uses a total amount of30members, including10beams of obverse section bent of the drying immersion cycle test:LM1、LM3,20beams of obverse section bent of the salt spray corrosion: LM-A、LM-B、LM-C、LM-D.
