Durabilitas Beton Sekat Kanal Terpapar Air Gambut Dan Air Laut

---

Canal blocking is one of the peat wetting techniques because of excessive groundwater level decline and can anticipate fires on peatlands. However, in the downstream part of the peatland, the canal blocking is also in direct contact with seawater on the other side. By getting two attacks (dual attack) so it is necessary to use high-durability concrete, one of which is by using pozzolan in the form of fly ash to get high-quality concrete.
This study aims to design a precast canal bulkhead concrete of high durability with a planned concrete quality of fc' 35 Mpa, with a water cement factor (fas) of 0.32, the cement used is PCC cement with a variation of 0% FA as a control and using 30 % FA by weight of cement. After receiving treatment with normal water for 28 days, it was then simulated by soaking in three different immersion tanks, namely peat water, 3.5% NaCl solution and mixing peat water and NaCl.
The results of the PCC concrete compressive strength test decreased after 91 days of immersion in peat water by 4.74%, 24.91% by immersion in NaCl solution and 15.95% by immersion in a mixture of peat water and NaCl solution. In PCC-FA concrete the compressive strength increased after 91 days of immersion by 26.53% in peat water immersion, 30.87% in NaCl solution immersion and peat water immersion mixed with NaCl solution. Visually, acid penetration has not occurred. Concrete has a very good density value of 5138.75 m/s on concrete 0 days of immersion. PCC-FA concrete sorptivity value < 0.2000 mm/min0.5. While the PCC-FA concrete FTIR test in 91 days of NaCl solution had a higher absorption frequency of 0 at each wave crest. Based on the results of the tests carried out, PCC-FA concrete with FA as much as 30% can increase the durability of concrete for concrete exposed to peat water and sea water.
