Corrosion Behavior of Reinforcing Steel Bar HPB235 in NaCl Solution Ying Wang1, Ping Li1, a 1Department of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang 471023, China aeappol@163.com Key Words: Reinforcing Steel Bar, Corrosion behavior, Corrosion rate, Mechanical properties Abstract: The corrosion behavior of reinforcing steel bar HPB235 in concrete structure in 0.5% NaCl solution was investigated and its mechanical properties were tested before and after corrosion.
Introduction The research on the duration of concrete structure, begun in 1940s, has been an important project in the field of civil engineering at present.
Nevertheless, in practical corrosion environment, the corrosion of reinforcing steel bar occurs at different extent, which leads to the weakening of concrete and ceaseless engineering accidents [2, 3].

According to existing data, calculated width of soil taken twice the width of the building can satisfy the engineering precision [2], and the thickness of the soil taken 1/2 of the width of the building can well simulate semi-infinite domain of soil[3],so the soil size taken in this paper is 72m×72m×36m.

Effect of Corrosion on Mechanical Properties of Reinforcing Bar HPB235 Ying Wang1, Ping Li1, a 1Department of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang 471023, China aeappol@163.com Key Words: Reinforcing Bar, Corrosion behavior, Corrosion rate, Mechanical properties Abstract: The corrosion behavior of reinforcing bar HPB235 in simulated concrete pore solution (3.5 wt.% NaCl solution) was investigated, and the tensile mechanical properties before and after corrosion were tested.
Introduction Reinforcing bar concrete is one of the most common modern building structures, and is widely used in military, industrial, agriculture and civil construction, etc.
Nevertheless, with the passage of time and the change of environment, the corrosion of reinforcing bar occurs at different extent because of the carbonization of concrete and the inrush of chloride, which leads to the weakening of concrete and ceaseless engineering accidents.
