ANALISA DAN KAJIAN EKSPERIMENTAL PENGARUH PENAMBAHAN SERAT BENDRAT (SERAT KAWAT) PADA DAERAH TARIK BALOK BETON BERTULANG
ABSTRACT: Rebars is the most
expensive material in the construction. Bendrat fiber / wire fiber was selected
material because aside from having the material factors - factors principles
concrete reinforcing, but also easily obtained. This experiment was done with
cylinders (15x30) and reinforced concrete beams (15x25x320 with addition of 2%
bendrat/wire fiber in the tensile’s area of reinforced concrete beam. The
result of this experiment showed that compressive strength of concrete increase
37.22% when using bendrat / wire fiber. However, a significant increase
occurred in tensile strength, that was 74.52%. The test were done to reinforced
concrete beams showed decreasing of deflection 35.26% and Increasing flexural
capacity 27.97%. Coefficient of comparison between of load test (P) and load
theory (Pn) of reinforced concrete beams without bendrat / wire fiber (normal
)is 0.9903 and with bendrat / wire fiber is 0.7335. Coefficient of comparison
between collapse load testing (P) and the analytical ultimate load (Pu) of
reinforced concrete beams without bendrat / wire fiber: coefficient (φ) = 1.6
and with bendrat / wire fiber: coefficient (φ) = 1.15.
