Study on Damaged Reinforced Concrete Beams Strengthened with Basalt Fiber Polymer Sheets Huanan He 1,a, Wei Dong 2,b State Key Laboratory of Hydrology Water Resources and Hydraulic Engineering Science, Hohai University, Nanjing, China State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology, Dalian, China ahehuanandl@163.com, b dlutdw@yahoo.com.cn, c Keywords： Basalt fiber; Strengthen; Preload; Under loading；Reinforced concrete beams Abstract: In practical concrete structures, once reinforced concrete beams serve in case of over cracking or are even damaged due to sudden overloading, it is necessary to repair or strengthened the damaged members for purpose of restoring the structural capacities and keeping the structures working well.
At present FRP strengthening technique is one of the most accepted methods available in civil engineering.
At present basalt fibers have been mostly used to strengthen various reinforced concrete structures or members, but further study on how to effectively use basalt fiber to strengthen damaged concrete members are still desirable for practical engineering.

Effect of Corrosion on Mechanical Properties of Rebar HRB335 Ying Wang, Ping Li a Department of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang 471023, China aeappol@163.com Key Words: Rebar HRB335, Corrosion behavior, Corrosion rate, Mechanical properties Abstract: The corrosion behavior of rebar HRB335 in simulated concrete pore solution (3.5 wt.% NaCl solution) and the tensile mechanical properties before and after corrosion were investigated.
Introduction Rebar concrete, one of the most common modern building structures, is widely used in industrial, agriculture and civil construction, etc.
Nevertheless, with the passage of time and the change of environment, the corrosion of rebar occurs at different extent, which leads to concrete weakening and engineering accidents.
