Durabilitas Beton Pofa Dengan Penambahan Silika Fume Di Air Gambut

---

ABSTRACT
This study examines the durability of PCC concrete and POFA concrete with the
addition of silica fume soaked in peat water. POFA is used as a cement substitute
with variations of 0%, 20% and 40% and the addition of silica fume is 10%. The
design compressive strength is 20 MPa. Observing the specimens was carried out
in normal water for 28 days and then immersed in peat water for 0, 7 and 28
days. The durability test that will be carried out is compressive strength, porosity,
sorptivity, weight change and UPV (Ultrasonic Pulse Velocity). The results of
testing the compressive strength of concrete at 28 days of immersion in peat have
increased 16.73% with 29.24 MPa in PCC concrete, 29.49% with 32.69 MPa in
0% POFA concrete, 17.58% with 25.77 MPa POFA 20% and 10.56% concrete
with 24.71 MPa in POFA 40% concrete. The porosity value of PCC concrete at
28 days of peat decreased by 6.55%. A decrease in porosity values also occurred
in POFA 0% concrete, POFA 20% concrete, and POFA 40% concrete by 20%,
26.78%, and 14.49% at 28 days of peat. The sorptivity of PCC and POFA
concrete with silica fume decreased with increasing immersion age. The weight
change in PCC concrete has increased along with the increasing immersion age.
The UPV test results increased at 28 days of peat. In PCC concrete the increase
was 0.96% with a speed of 4329.93 m/s. In POFA 0% concrete and POFA 40%
concrete, the increase was 3.34% and 0.41% with a speed of 4825.20 m/s and
4492.00 m/s. While for 20% POFA concrete, UPV testing results decreased by
2.53% with a speed of 4465.60 m/s at the age of 28 days of peat. Based on the test
results, it can be concluded that replacing cement with POFA and adding silica
fume to concrete has a positive impact on the compressive strength and durability
of concrete in peat water.
Key words: Durability, POFA, silica fume, peat water
