Analisis Metode Split Tensile Test Komposit Laminat Hybrid Jute E-Glass Terhadap Kekuatan Tarik Belah Beton Kolom Silinder

Abstract

Tujuan penelitian ini ialah untuk Mengetahui kekuatan tarik beton kolom silinder (BKS) dengan metode uji tarik belah (split tensile test) akibat pemberian selubung komposit laminat hibrid jute e glass (KLHJG), Analisis validitas data dengan metode data terdistribusi normal (DTN) terhadap hasil uji kekuatan geser selubung KLHJG sebagai penguat BKS, Analisa pengaruh pemberian selubung KLHJG terhadap kekuatan tarik BKS. Metode yang digunakan adalah split tensile testdan Data terdistribusi Normal. Alat yang digunakan yaitu Universal Testing Machine, dan bahan baku yang digunakan lembar jute dan lembar e-glass,resine epoxy dan hardener,semen,pasir , air dan krikil. Hasil penelitian ini ialah kekuatan tarik belah maksimum rata-rata diperoleh pada selubung KLHJG variasi ( JGJG ) yaitu 8,333 MPa hasil analisis terhadap fungsi kerapatan variasi terhadap seluruh data uji menunjukkan bahwa data-data hasil eksperimental tersebut adalah terdistribusi secara normal. pemberian selubung KLHJG pada spesimen beton silinder terbukti dapat mempengaruhi peningkatan kekuatannya tarik belahnya. In this study, reinforcement of the concrete structure was done by coating it with a laminate composite material from a combination of reinforcement from natural materials (woven jute cloth sheets) and synthetic materials (woven e-glass fiber sheets). The purpose of this study was to determine the split tensile strength of cylindrical column concrete (BKS) using the split tensile test method due to the application of e-glass laminate hybrid composite sheath (KLHJG), to analyze the validity of the data using the normally distributed data method (DTN). on the results of the shear strength test of the KLHJG sheath as reinforcement for BKS, and analysis of the effect of applying KLHJG's sheath on the tensile strength of BKS. Specimens were printed based on the ASTM C496 test standard by immersion in clean water for 28 days and drying in the open air for 28 days. The KLHJG variation consists of JGJ, JJG, JJJG, JGJG, and GJGJ. Each variation consists of 3 repetitions of the test. The process of providing KLHJG casings to BKS uses the Vacuum Bagging method. Data validity uses the probability density function method. The results of the study show that the provision of KLHJG can increase the split tensile strength by up to 800%. Thus, the KLHJG application has the potential to be applied as a BKS booster.
