Abstract: Ultra-High-Performance Concrete (UHPC) as the new generation of concrete has attracted
many researchers to be applied for construction materials, like roof shells, bridges and
buildings. Recently the authors have conducted research to apply UHPC reinforced by
Polypropylene Fiber named UHPPFRC for boat skin. This study is conducted with the main
objective to test the strength of the boat skin made from UHPPFRC. The UHPPFRC skin will
behave structurally as shell, named on this study as UHPPFRC macro shell. The UHPPFRC
macro shell with the thickness only 5 mm will be studied under static loading test. The
influence of shell curvature and the volume of polypropylene fibers to the strength and
deflection of the test specimen will be studied. Testing is done by putting three static point
loads and two dials to determine the deflection. 3 specimens of UHPPFRC macro shells with
concrete strength fc’120 MPa will be provided for investigation. The loading test result of
UHPPFRC macro shell with curvature of 15 cm and 0.8% volume polypropylene fibers had
ultimate load until 540 N (52.42 kg) or 11 times its self-weight and maximum deflection of
0.95 mm. Meanwhile UHPPFRC macro shell with curvature of 20 cm and 0.8%
polypropylene fibers had higher ultimate load, that was 837 N (83.76 kg) or 14 times its self-
weight and maximum deflection of 1.186 mm. To investigate the influence of Polypropylene
volume, UHPPFRC macro shell with curvature of 20 cm and 0.48% polypropylene volume
had been tested. Its test load reached ultimate load of 654N (65.4 kg) or 11 times its self-
weight and a maximum deflection of 0.898 mm. The test results showed that the UHPPFRC
can be applied for shell structure effectively, like boat skin. Only with the thickness 5 mm the
UHPPFRC macro shell can bear load until 14 times its self-weight.
