Abstract: |
Fiber reinforcement
is an effective approach to improve flexural behavior of concrete
as a brittle material. In a thin section, fiber orientation
is not totally random and tends to form a 2-dimensional orientation.
The method of slurry infiltrated fibered concrete (SIFCON)
was implemented using 160 x 40 x 40 mm specimens. In this research,
the ultimate flexural strength of fiber-reinforced concrete
in thin sections has been studied. The results showed a significant
increase in ultimate flexural strength and fiber efficiency,
compared with fiber-reinforced concrete with randomly oriented
fibers. |
