| Abstract: |
| Fibers are added to concrete/shotcrete to enhance the ductility,energy absorption ability and crack resistance,and prevent crack development.In order to estimate the toughness of fiber reinforced concrete(FRC) and establish Chinese Guideline of FRC,many experiments of flexural toughness for SFRC beams were done according to different national guidelines.Based on test results,the comparison of the foreign flexural toughness test methods were carried out.It provides basis for the establishment of guideline of FRC in our country. |
