PROBLEM TO BE SOLVED: To evaluate hydrogen embrittlement characteristics taking into consideration the damage of a reinforcing-bar in a manufacturing process of a reinforced concrete structure.SOLUTION: A reinforcing-bar is taken out of a reinforced concrete structure, and the reinforcing-bar is immersed in a neutral or alkaline solution. Then, while electrochemically charging hydrogen to the reinforcing-bar immersed in the solution, a dynamic load is applied thereto so as to conduct a rupture test. Thereby an effect due to the difference of a damage degree by a material for the reinforced concrete structure to hydrogen embrittlement characteristics can be quantitatively measured.SELECTED DRAWING: Figure 1 |
