Abstract
Indonesia merupakan salah satu negara yang memiliki
kepadatan penduduk tertinggi di dunia. berkembangnya
infrastruktur tersebut, muncul pula berbagai masalah seperti
kurang diimbanginya perkembangan infrastruktur dan
pertumbuhan di bidang peraturan keselamatan kebakaran.
Ketimpangan laju pertumbuhan tersebut, pada akhirnya memicu
tingginya angka kebakaran bangunan. Kebakaran yang terjadi
pada bangunan seringkali menyebabkan kerusakan pada elemenelemen
strukturnya. Kualitas dan kekuatan beton portland akan
mengalami penurunan seiring dengan kenaikan suhu dan lama
terjadinya kebakaran tersebut. Untuk itu perlu dikembangkan
bahan struktur lain yang memiliki ketahanan lebih tinggi seperti
beton geopolimer.
Selain memiliki ketahanan yang tinggi, beton geopolimer
juga ramah lingkungan. Beton geopolimer tidak menggunakan
semen Portland yang dikenal sebagai salah satu pengahasil gas
CO2 terbesar. Pada penelitian ini benda yang diuji adalah pasta
geopolimer disusun dari campuran abu terbang tipe C dari
PT.Petrokimia Gresik, alkali aktifator berupa sodium hidroksida
6, 10 dan14 Molar .Benda uji berupa silinder 2,5 cm x 5 cm dan
kubus 5 cm x 5 cm akan melalui proses perawatan pada suhu
ruang sampai umur 28 hari dan di uji bakar pada suhu
200oC,600oC dan 1000oC selama 4 jam. Kemudian untuk
mengetahui kuat tekan dan ketahanan, maka dilakuakan
pengujian kuat tekan, porositas, UPV, dan hammer test.
Hasil penelitian ini menunjukkan bahwa Kuat tekan pasta
geopolimer ( 6,10 dan 14 molar) pada suhu 2000 C lebih kuat
dibanding perawatan suhu ruang. Kembali turun kuat tekannya
pada suhu 6000 C dan benda uji rusak pada suhu 10000 C. ===== Indonesia is a developing country which has the highest
population density in the world, lack of Infrastructure
development gives sorts of problems, such as low adaptable
infrastructure development and less innovation of fire safety
regulations. Both of two reasons that have been mentioned can
impact high rates of fire accident. As we know that fire accident
will make some elements the of building structure become
weaker. Quality and strength of Portland concrete can be
decreased not only by the increasing temperature but also about
duration of fire accident. It is necessary to improve other
structural material that has a higher resistance such an example
is geopolymer concrete.
Moreover, geopolymer concrete is high resistance of high
temperature and also environmentally friendly. Geopolymer
concrete doesn’t contain Portland cement which is one of the
highest CO2 gas producer. On this research, specimen that we
used is geopolymer pasta that composed of fly-ash type C from
PT. Petrokimia Gresik, the alkali activator is sodium hydroxide
6,10,14 Molar. Forms of the specimen are, cylinder 2,5 cm x 5 cm
and in a form of cube which dimension is 5 cm x 5 cm. Both will
have treatment process in room temperature up to 28 days.
Specimens will be tested in a burning process on
200°C,600°C,1000°C temperatures for 4 hours. Then, some
methods to measure the compressive strength and resistance are
compressive strength test, porosity, UPV and also hammer test.
The result of this research shows that, compressive test of
geopolymer pasta (6,10,14 Molar) on 200°C is stronger than in a
room temperature treatment. The compressive strength was
decreased on 600°C and wrecked on 1000°C.
