Durabilitas Beton Geopolimer Hybrid Faba Dengan Penambahan Portland Composite Cement Di Air Gambut

---

ABSTRACT
Geopolymer hybrid concrete is formed from materials containing alumina
and activated silica using an alkali activator with the addition of portland cement
to produce heat of hydration so as geopolymer concrete treatment can be carried
out at room temperature. This research aims to study the durability of geopolymer
hybrid FABA concrete with the addition of PCC after exposed to peat water for 0,
7, 28, and 91 days. FABA hybrid geopolymer concrete uses an activator solution in
the form of 12M NaOH and Na2SiO3 with Ms 2.5, and the addition of PCC cement
by 15% of the weight of FABA. The control concrete is normal PCC concrete with
a design quality of 20 MPa. The results of testing the compressive strength of PCC
concrete until the age of 91 days of peat water experienced an increase in
compressive strength of 24.2% with 29.14 MPa, as well as FABA hybrid
geopolymer concrete increased by 7.87% with 24.28 MPa. The porosity of both
types of concrete decreased at the age of 91 days of peat water, where the decrease
in PCC concrete was 21% and FABA hybrid geopolymer concrete was 7.88%. The
results of the PCC UPV test at the age of 91 days increased by 1.3%, as well as the
FABA hybrid geopolymer concrete increased by 12.71%. Changes in weight of
PCC concrete at the age of 91 days of peat water increased by 0.048%, as well as
FABA hybrid geopolymer concrete increased by 0.066%. The sorptivity value of
PCC concrete increased by 27.63%, while the FABA hybrid geopolymer concrete
decreased by 48.53%. The half-cell potential test results showed that PCC concrete
at the age of 91 days of peat water decreased the potential difference value to
372mV, as well as the FABA hybrid geopolymer concrete potential difference value
to 330.27mV. The results of the AAS test at 28 days of peat water showed that the
concentration of heavy metals contained in the peat water immersion of the FABA
hybrid geopolymer concrete was below the threshold permitted by PP No. 101 of
2014. Based on the results of the tests carried out, FABA hybrid geopolymer
concrete has good durability when exposed to peat water.
