| Abstract |
In this study, the flexural strength of Concrete slabs mixed Macro synthetic fibers were evaluated according to foreign standards and
preceding research. The mechanical properties of concrete mixed with macro synthetic fibers were evaluated through material tests. The
flexural strength and residual strength of the slab were calculated and evaluated for comparison by referring to foreign standards and previous
studies. After comparative evaluation, the evaluation result was confirmed through a structural test, and the effect of macro synthetic fibers
on the structural performance was analyzed. The contents were analyzed for neutral axis, flexural strength, ductility, and crack control
performance. As a result of the experiment, the flexural strength of the slab was increased by reinforcing macro synthetic fibers. In addition,
crack control performance and ductility were also increased. |
