KAJIAN PENGARUH PENAMBAHAN SERAT BAMBU ORI TERHADAP KUAT TEKAN DAN KUAT TARIK BETON
ABSTRAK: The addition of fiber
in concrete admixture has been proven be able to improve the concrete quality.
There are many researches about fiber concrete has been done by using many
fiber materials. Bamboo has great opportunity to be a fiber material in
concrete admixture, because of its special characteristic. The price of Ori
Bamboo is also usually cheaper than the other type of Bamboo. This research was
experimental research of fiber concrete, which used the fiber of Ori Bamboo.
The objective of this research was to study the impact of using the fiber of
Ori Bamboo on the strength of concrete.
This research used normal mixing of concrete with additional fiber, which
was made of Ori Bamboo. It has 0.5 mm thickness, 0.5 – 1 mm wide, and 2 cm
length. The variations amounts of fiber are 1%, 1.5% and 2% of the total weight
of cement. The test of compressive strength and tensile strength were done with
standard cylinder, 28 days of age. The
result of this research shows that the higher percentage of fiber, the lower
viscosity of admixture. The addition of fiber
by 1%, 1.5%, and 2% give
increasing of 17.85%, 16.45% and
3.14% of concrete compression
strength, as well as 4.85%, 30.58% and
19.42% of concrete tensile strength.
