Banana Fiber-Reinforced Geopolymer-Based Textile-Reinforced Mortar

Confinement of Concrete Using Banana Geotextile-Reinforced Geopolymer Mortar

“…Factors considered in creating the DM were: the water-to-solid ratio of 0.2; the NaOH-to-Na2SiO3 ratio of 0.54; the FA-and-SiO 2 -to-sand ratio of 1.5; and the fact that 5% of SiO 2 and 1% of BFs were utilized. This DM is based on the studies of Quiatchon et al [31] and Pilien et al [27]. Table 3 shows: the 6 BGT-RGM designs and the control samples with 3 samples each; the thicknesses of the mortar, which are 12 mm and 20 mm; and the grid spacings, which range from 15, to 20, to 25 mm.…”

“…Also, the PVC molds were used to ensure that there would be a 10 mm gap on both the top and the bottom of the concrete cylinder. After 24 h, the BGT-RGM confined concrete samples were wrapped with plastic cling wrap, both to ensure that alkali activators would not spill, and to avoid the occurrence of efflorescence that can significantly weaken the BGT-RGM [27].…”

“…Textile-reinforced mortar (TRM) has emerged as a practical and efficient technique for enhancing the performance of concrete structures. The confinement provided by TRM leads to significant improvement in the concrete's axial load capacity and overall durability [1]. However, traditional TRMs and fiber-reinforced cementitious matrices (FRCMs) are commonly made from ordinary Portland cement (OPC) matrices and synthetic fibers (SF).…”

“…The types and design mixes of geopolymer which affect the composite's durability, that in turn influence the formation of cracks, were put forward in a previous study of Wyom Paul et al [26]. In this study, the design of the experiment was adopted from the work of Pilien et al [27], who performed an optimization on the fly ash-based banana fiber reinforced geopolymer mortar (BFRGM). Furthermore, based on the intensive review of Koustas et al [22] on TRMs with synthetic fibers, the compatibility of BGTs with the BFRGM were also investigated.…”
