Abstract

Uniaxial tensile properties of a SHCC can be confirmed by simply fabricating prism specimens at the job site and molding those later into a dumbbell shape for uniaxial tension testing. Level of skill in fabricating dumbbell-shaped specimens and the use of vibratory consolidation led to no significant difference in the uniaxial tension test results. The variances and means of the uniaxial tension test results of specimens molded in this manner showed no significant difference from those of monolithically molded dumbbell-shaped specimens. Also, changes in the fiber content of the molding material from 1.25% to 0.5% in steps of 0.25 percentage points had no significant effect on the test results, leading to test results equivalent to those of monolithically molded dumbbell-shaped specimens.
