Komposit laminat jute, beton kolom silinder, kekuatan tarik belah, persentasi pola retakAbstrak
Tujuan studi ini ialah mendapatkan pola kerusakan spesimen beton kolom silinder (BKS) diperkuat komposit laminate jute (KLJ) berdasarkan hasil uji Split Tensile Test (Uji tarik belah), mengetahui fenomena pemberian penguat bahan komposit laminat jute terhadap beton kolom silinder terhadap persentase pola retak (PPR) spesimen, dan menganalisis perbandingan antara kekuatan tarik belah (KTB) dan PPR. Spesimen uji dicetak berdasarkan standar uji ASTM C496 dengan metode Vacuum Bagging. Variasi spesimen terdiri dari 1 hingga 4 lapis KLJ dan satu variasi tanpa selubung KLJ sebagai spesimen kontrol. Pengujian tarik belah menggunakan alat uji UTM dengan masing-masing variasi dilakukan 3 kali perulangan. Pengamatan dan perhitungan PPR dikerjakan dengan bantuan software Adobe Photoshop. Hasil studi menunjukkan bahwa semakin besar nilai KTB maka semakin besar pula PPR yang terjadi. Peningkatan PPR pada masing-masing KTB dilaporkan dalam artikel ini.
