Abstract
Confinement of concrete using different materials and procedures is an effective method of strengthening weak and deteriorated concrete structural members especially those under axial compression. Recently, textile reinforced mortar (TRM) has become popular as a confinement material. TRM consists of high strength fibers with open mesh grid configurations bonded by inorganic matrix like lime or cement-based mortars. TRM usually contains environmentally harmful materials that can affect the ecosystem. To lessen the environmental impact of traditional materials, a more environmentally friendly confinement using natural fibers and cement-free mortars has become a subject of recent studies. To address the challenge of developing a confinement material for axial compression members that is effective and environmentally friendly, a novel banana geotextile-reinforced geopolymer mortar (BGT-RGM) was developed in this study. BGT-RGM is composed of banana geotextile (BGT) and engineered geopolymer composite (EGC) reinforced with 10mm short banana fibers (BF). The EGC is a fly ash (FA) based geopolymer reinforced with 10mm short BFs and the banana geotextiles are fabricated from twined 2mm diameter BF cords. The experimental study on the development of BGT-RGM involves various phases. The first phase, which is Banana Fiber Extraction and Treatment aims to optimize a treatment solution that will enhance the physical and mechanical properties of banana fiber suitable as reinforcement. After treatment, mechanical, physical, chemical, and microstructural analysis of the treated and untreated banana fibers were conducted after the elimination of fibers through manual testing of fibers to determine the top performing banana fibers that will be used for reinforcing the EGC. After nine different treatment solutions with 2, 4 and 6 % of sodium hydroxide (NaOH) within 2, 4 and 6 hours, phase 1 resulted to selecting a length of short fibers of 10mm to be used as reinforcement of the EGC to reduce the brittleness of geopolymer and prevent the occurrence of macro cracks. The next phase involves the optimization of plain geopolymer mortar (PGM) and EGC mortar was carried out to find the optimum mixtures to be reinforced with top performing fibers during the manual and machine testing of fibers. The PGM and EGC mortar were prepared by using FA and silica fume (SF) as binders and sand as filler, then it was activated by an alkali solution composed of NaOH and WG. With the inclusion of silica fume, which is commonly used pozzolanic material, in the geopolymer, the durability of the composite was enhanced. There
