Tech, Department of Civil Engineering, Chennai, India ABSTRACT Nano-technology is useful to study hydration and alkali silicate reactions of concrete which plays a major role to arrest segregation and micro cracks. In the present study Mechanical properties of M50 grade of Conventional concrete (CC) and Nano- silica concrete (NSC) were studied. Experimental results predicts that NSC achieves superior properties than CC in strength criteria. This paper represents flexural behavior of CC and NSC in-filled in light gauge rectangular box cross sections under the criteria of pure bending. Here in this project used thickness of light gauge steel beams are 1.6 mm and 2.0 mm. Hence to arrest local buckling and to get internal support in cold formed steel members, these are infilled with concrete. It can increases the stiffness and flexural strength of the member by the moment of inertia of section. Hollow, conventional concrete in-filled and Nano silica concrete infilled beams in pure bending are to be tested until failure with respect to Zone of minor axis. Deformation and extensive strain results are calculated at zones of compression and tension. By this thesis work we can conclude that the NSC in-filled sections take more load than hollow and CC in-filled beams when it is subjected to loads about their minor axis. By this research work it is found that, when hallow and CC infilled beams are compared with Nano-silica concrete infilled (with 4% of Optimization) beams they have low reliable structural properties. When compared with light gauge steel beams of hallow and infilled CC, light gauge steel beams of NSC with 4% of optimization shows best ductility performance by Moment-strain plots. Key words: Nanotechnology, Nano-silica (NS), Conventional Concrete (CC), Nano Silica concrete (NSC), compressive strength, flexural strength, split tensile strength, impact resistance test and modulus of elasticity, light gauge steel beam, flexural strength and stiffness.
