Flexural behavior of warp knitted textile reinforced concrete impregnated with cementitious binder

Abstract

Textile reinforced concrete is a novel and high performance material which is gaining popularity in the recent days due to its high potential to effectively improve the strength and durability of concrete structures. Owing to absence of coarse aggregate and presence of high cement paste content, TRC has properties that are different from conventional concrete. In this paper, performance of three different types of binders ie., Organic binder, Inorganic Geopolymer binder and epoxy binders for compressive and split tensile strengths was presented and were compared to assess their effectiveness in enhancing properties by testing 12 mortar cubes of size 70.6 mm and 6 mortar cylinders of size 75 × 150 mm. The efficaciousness of weft insertion warp-knitted textile fabrics of ARG and Basalt on the Compressive strength, flexural strength, ductility, toughness, and failure modes were evaluated experimentally by investigations carried out on 4 RCC beams. The effect of the thickness of Textile reinforcement is also studied by using textile layers of thicknesses of 5, 10, and 15 mm. The results indicated that application of basalt textiles fabric using cementitious binder exhibit higher strength and ductility. Basalt textile is more preferable due to its eco-friendly properties. The experimental findings are validated through analytical equations, ensuring the reliability of the study.
