| Research Abstract |
The purpose of this paper is to develop the material design of Strain Hardening Cementitious Composites (SHCC) which has high strength and toughness under tensile stress. For this purpose, it is necessary for appropriate kinds of fiber and mix proportion of matrix to be chosen and for constitution of conditions to be clarified. The present study aims to clarify combined effects of fiber cocktail on the tensile properties under uniaxial tensile stress of SHCC using steel fibers and synthetic fibers. In the result, firstly, it was revealed that tensile strength and toughness can be enhanced by mixing steel and synthetic fiber of appropriate quantity. Finally, mixing enough steel fiber and lowering the water-binder ratio, the tensile strength and toughness of the composites increases by dispersing high strength to depend on steel fiber.
