Behaviour of Nano Silica Powder and Hybrid Fiber Reinforced Concrete Beams with Cyclic Loading

the various properties of concrete are influence by nano-silica is obtained by replacing the cement with various percentages of nano-silica and with natural hybrid fibres. Nano-Silica powder is used for a partial replacement of cement, the range of 2%, 2.5%, 3%, 3.5%, 4% and hybrid fibre range of 0.5%, 1%, 1.5%, 2% and 2.5% for M25 grade of concrete Mix. Specimens are casted by using Nano-Silica concrete and NHFRC. Laboratory works were conducted to find the ductility strength of concrete at the age of 28 days. Moreover, the density of concrete is reduced when compared to control concrete. Thus, the results of partial replacement of cement with Nano-Silica & NHFRC are higher strength and reduction in the permeability when compared to controlled concrete. The partial replacement of Nano-Silica is more than 3% & 1.5% of NHFRC. Determine the results in the reduction of various physical and mechanical properties of Nano-Silica concrete.
