| Research Abstract |
This research was conducted to develop a new robust fiber reinforced cementitious material under the multi directional stress field based on HPFRCC that shows high ductility in tension with multiple cracking. Coarse aggregate and steel fiber were put in the HPFRCC to improve the shear performance after the cracking. Through the experimental investigations at the material scale, appropriate ratio of the inclusions was proposed. To apply this material to structure, static and fatigue tests of beam were carried out to verify the applicability.
