Abstract

Nowadays, Non Destructive Tests have been applied in many quality
evaluations of existing concrete structures. One of the Non Destructive Tests (NDT)
is based on Ultrasonic Pulse Velocity (UPV). The use of UPV method among others
are to estimate the strength of concrete, to detect the presence of crack, to measure
the homogeneity of concrete, the thickness of concrete slab, and also to estimate the
diameter of the embedded steel reinforcement. The NDT technique will apply on this
research. This research used 24 cylinder test samples in four groups, which were
reference cylinder (SR), cylinder-1 (S-01) with 0.5 kg/m3 of fibers, cylinder-2 (S-02)
with 1.0 kg/m3 of fibers and cylinder-3 (S-03) with 1.5kg/m3 of fibers. Those cylinders
were of 150 mm in diameter and 300mm in height. The Ultrasonic Pulse Velocity
(UPV) test was conducted with direct test method. The data are then analyzed using
statistical program. The test result showed that the addition of polypropylene fibers
optimum and pulse velocity were of 1kg/m3 and 3,19km/s respectively. The increase
pulse velocity transmitter higher on variation of fibers 1kg/m3 is 9,12% in comparison
to reference cylinder. The statistical test indicated that the signifinance value (2-
tailed test) is homogeneity sample. This means that the ultrasonic pulse velocity
method can used to knowing of homogeneity self compacting mortar using fibers.
