| Outline of Final Research Achievements |
In this study, following new findings related to the roles of short fiber in FRC before cracking were obtained; 1) nondestructive method to clarify the fiber distribution in the specimen was developed. 2) method to estimate fiber distribution and orientation was proposed. 3) creep behavior of FRC in compression was assessed. 4) corrosion protection function provided by steel fibers for rebar inside of FRC was clarified.
