Tensile behaviour of glass fibre textile reinforced mortar with fine aggregate partially replaced by fly ash

Abstract Textile Reinforced Mortar (TRM) is an innovative technology in which high strength textile is embedded in cementitious mortar. The cementitious mortar used for TRM must possess high strength, stiffness and ductility for strengthening applications. The present study was conducted on glass fibre textile reinforced mortar by fine aggregate partially replaced by fly ash. The cementitious mortar was developed with fine aggregate partially replaced by varying percentage fly ash and compressive strength was evaluated. The optimum compressive strength and tensile strength was obtained at fly ash replacement percentage of 60% of the fine aggregate. Tensile strength of glass fibre TRM laminates was evaluated for different thickness of the laminate. The strength and stiffness of TRM specimens increases as the percentage fine aggregate replacement increases. As the thickness of the TRM specimens increases, the tensile capacity increases linearly up to 10 mm thickness, beyond which the rate of tensile strength development decreases.
