Confinement of Concrete Using Banana Geotextile-Reinforced Geopolymer Mortar

Geopolymer, a sustainable alternative to ordinary Portland cement (OPC), offers reduced embodied energy, lower carbon emissions, enhanced durability, eco-compatibility, and waste valorization potential. In confining structural members, geopolymer still has limitations with respect its brittleness other properties. Enhancing the properties of by adding banana fibers (BF) fly ash (FA) form geotextile-reinforced mortar (BGT-RGM) as material, is investigated in this experimental study. BGT-RGM textile-reinforced varying thickness BF-reinforced (BFRGM) through NaOH-treated 10 mm BFs 2 geotextile (BGT) having varied grid spacings. To develop BGT-RGM, physical, mechanical, chemical were determined, while BFRGMs evaluated for compressive dog-bone tensile strengths, workability, scanning electron microscopy (SEM) imaging, thermogravimetric analysis (TGA). The BGT-RGM-confined unconfined concrete evaluated, strength variations imparted confinement reflected on stress-strain curves. local crack formation mode failure was also determined patterns during an axial load test. 20 BFRGM 15 spacings, exhibited 33.3% 33.1% increases strength, respectively. Future investigations towards development application are discussed.
