Abstract: ABSTRACT OF THE INVENTION The present invention discloses a sustainable low-carbon Textile Reinforced Mortar (TRM) lamina system (100) developed for masonry strengthening applications. The developed TRM system (100) comprises a cementitious mortar matrix (112a) incorporating Ordinary Portland Cement (OPC 53 grade) (106a), ground granulated blast furnace slag (GGBS) (106b), and fly ash (106c) as binder materials (106), together with manufactured sand (M-sand) (108a) partially replaced by quarry dust (108b). Basalt textile mesh reinforcement (110) having a mesh size of 25 mm x 25 mm is embedded within the mortar matrix (112a) to improve tensile resistance, crack control, and structural performance. The developed mortar matrix (112a) is prepared with a water-to-cementitious material ratio of 0.40 and a superplasticizer (200) dosage of 0.5% by weight of the total binder content to achieve the required workability and consistency suitable for textile impregnation and composite fabrication. The developed TRM composite system (112b) exhibited improved compressive, flexural, and tensile performance characteristics together with enhanced reinforcement utilization efficiency. Durability investigations (118) indicated improved resistance against chloride ion penetration, oxygen permeability, water ingress, and capillary absorption behaviour. The strengthened brick masonry prism specimens (126) demonstrated improved compressive, flexural, flexural bond, and shear bond performance compared to unreinforced brick masonry prism specimens (124). The developed lowcarbon TRM lamina system (100) achieved an approximate 43% reduction in embodied carbon emissions compared to conventional cement-rich strengthening systems, thereby providing a sustainable and durable solution for masonry strengthening applications. 30 Figure 1 shows the overall methodology adopted for the development and application of the low-carbon Textile Reinforced Mortar (TRM) lamina system for masonry strengthening applications.nd retrofit
