| Outline of Final Research Achievements |
This research was studied about materials design of the very high-strength strain hardening cement composite of more than 20 MPa of tensile strength.A result showed that it's effective in improvement of the tensile strength to mix 2 kinds of steel fiber different in the physical properties in a matrix.In especially, the influence on the tensile strength and the toughness is very big for the mixture amount of the long steel fiber.The tensile strength improved remarkably with increase of the mixture amount of the long steel fiber at the reach to the 2Vol.%.
Moreover, it was examined material design method. Tensile performance of mixed two different fibers at the reach to the 5Vol.%. it was revealed by summing the tensile performance at a single entry of each of the fibers is approximately be estimated.
