Abstract

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.

Abstract

The purpose of this study is to calculate the amount of energy that can be absorbed (toughness) of the material based on the graph of the results of the split tensile test of cylinder column concrete specimens (BKS) reinforced with laminated jute composite (KLJ) and analysis of the comparison between split tensile strength (KTB) and material toughness from the results split tensile test of BKS specimen reinforced by KLJ. The test specimens were printed based on the ASTM C496 test standard using the Vacuum Bagging method. Specimen variations consist of 1 to 4 layers of KLJ and one variation without KLJ sheath as a control specimen. The split tensile test used the UTM test tool with each variation being carried out with 3 repetitions. Calculation of Material Toughness Energy (EKB) using the Trapezoidal Numerical Integration method. The results of the study showed that giving KLJ boosters to BKS was able to increase EKB up to more than 1000% starting with 2 layers of sheathing. Thus the provision of KLJ to BKS can be recommended as a strengthening material for concrete column structures.
